Collating Sequence The EBCDIC and ASCII Environments http://www.simotime.com Copyright © 1987-2010 SimoTime Enterprises All Rights Reserved |
| Table of Contents | Version 09.05.17 |
The sorting or collating sequence for an EBCDIC environment is not the same as the sorting or collating sequence for an ASCII environment. The hexadecimal values used to represent the character sets that may be printed or displayed are different. When creating reports that are sorted by an alpha-numeric field (with or without special characters) the sequence of the presentation of information will be different. The major difference is the numbers (or digits) are sorted after the alphabet (with lower case being sorted before upper case) for the EBCDIC environment. The numbers (or digits) are sorted before the alphabet (with upper case being sorted before lower case) for the ASCII environment. The special characters will also be sorted differently as shown later in this document. This problem can usually be resolved by explaining the difference to the business users before an application is migrated between the two environments.
A bigger problem is the potential exposure for a failure in the logic of a program because of the differences in the collating sequence. For example the following logic will work fine in an EBCDIC environment but will fail in an ASCII environment.
| If BYTE-ONE is less than a SPACE-CHARACTER or Greater than DIGIT-NINE then BYTE-ONE is non-printable |
For more informationj about the potential for logic failures refer to the Possibilities and Considerations section of this document.
This suite of programs will show the differences between the EBCDIC and ASCII collating sequences. It also provides an example of possible logic failures in COBOL source code. This example is in COBOL but the failure would occur with other languages.
The COBOL programs are written using the VS COBOL II dialect and also work with COBOL for MVS and COBOL/370. A JCL member is provided to run the job as an MVS batch job on an IBM mainframe or as a project with Micro Focus Mainframe Express (MFE) running on a PC with Windows. A Windows Command (.CMD) file is provided to run the job on a PC with Micro Focus Net Express. This program may serve as a tutorial for new programmers and as a reference for experienced programmers. Additional information about data migration or data file conversion s provided in the Downloads and Links to Similar Pages section of this document. Our thanks to Larry Simmons of Micro Focus for providing us with much of the information in this document.
The following is a list of the functions provided in this example.
| 1. | Show the sequencing for EBCDIC and ASCII environments. |
| 2. | Show how to create a file for the full, printable character set. |
| 3. | Show an example of source code that will produce different results between the EBCDIC and ASCII environments. |
| 4. | Show how to run the application on a mainframe using JCL. |
| 5. | Show how to run the application on a Windows platform using a .CMD file. |
A JCL member (CBLCLTJ1.JCL) for the mainframe or a CMD file for the Windows environment (CBLCLTE1.CMD) defines and executes a five step procedure. The first step will delete any files created in a previous run. The second step will create a sequential file consisting of eighty-byte records with the first position containing a printable character. The third step will read the file, test the character in the first position of a record for being a valid printable character and write the results to an output file (Note: this step will work correctly in an EBCDIC environment but fail in an ASCII environment). The fourth step will sort the file (Note: this step will produce different sequencing for an EBCDIC or ASCII environment). The fifth step will read the sorted file, test the first position for a valid printable character and write the results to an output file (Note: this step will work properly in an EBCDIC environment but fail in an ASCII environment. Also, the sequence of the presentation of the data will be different between the two environments).
The following is an example of the sequential file that is created (COLLATE1.DAT for EBCDIC and COLLATE1.TXT for ASCII) that shows numbers, the alphabet in upper case, the alphabet in lower case and the special characters.

The preceding table is then sorted by position one (1) and produces a different sorting sequence for the EBCDIC-encoded and ASCII-encoded environments.
The following shows the programming logic that works in an EBCDIC-encoded environment and fails in an ASCII-encoded environment.
* The following logic will produce different results
* when in an EBCDIC or ASCII environment.
* This is because of the difference in the collating
* sequences of the two environments.
if COLLATE1-FIRST-BYTE < SPACE
or COLLATE1-FIRST-BYTE > 9
move 'NOT Printable' to COLLATE2-RECORD(16:13)
else
move 'Printable AOK' to COLLATE2-RECORD(16:13)
end-if
* End of example for logic differences
The following shows a side-by-side comparison of the results of the sorting and the programming logic that works in an EBCDIC environment and fails in an ASCII environment.

This section describes some of the possible problems that may occur when moving from an EBCDIC-encoded environment to an ASCII environment. Some coding changes may be required to get an application to produce the same results in both environments (reports and other output will most likely be in a different sequence when the fields that deternine the sort sequence is alpha-numeric).
The section will list of some of the items to look for during an EBCDIC to ASCII conversion. The list uses the term "half-a-range" check and is used to describe the following comparison logic.
The following will require extra time in the conversion process.
| 1. | Logic that processes alpha-numeric values and does half-a-range check using the “IF” or “EVALUATE” capabilities of COBOL may work in an EBCDIC-encoded environment and fail in an ASCII-encoded environment. | ||||||||||
| 2. | The INCLUDE or OMIT statements in the SORT utility program that do half-a-range check for alpha-numeric values may work in an EBCDIC-encoded environment and fail in an ASCII-encoded environment. | ||||||||||
| 3. | Tables that are hard-coded in COBOL and are accessed using a binary search (i.e. SEARCH ALL) and the search argument is alpha-numeric may work in an EBCDIC-encoded environment and fail in an ASCII-encoded environment. | ||||||||||
| 4. | Items that are alpha-numeric and use the technique of comparing for 999999 to indicate end of table or last record in a file will work in EBCDIC-encoded environments but fail in ASCII-encoded environments. | ||||||||||
| 5. | When working with international character sets (i.e. accented characters such as the umlat and tilde) be aware the upper case “Y” with the umlat is x’FF’ in EBCDIC and this will get converted to x’9F’ which is the ASCII equivalent. This could cause a conflict if the actual value is used as a high-value and should not be converted. | ||||||||||
| 6. | The use of hexadecimal coding techniques (i.e. x’C1’). This is sometimes used in COBOL and is required with the ALTSEQ statement in the SORT utility. Note: The ALTSEQ is frequently used on the mainframe to do a case-insensitive sort. | ||||||||||
| 7. | During the data file transfer process if MFA is not used (i.e. FTP is used) the following will require extra consideration.
|
||||||||||
| 8. | Data that is sequenced by an alpha-numeric key or sorted based on the content of an alpha-numeric field may be presented in a different sequence. | ||||||||||
| 9. | Data that is sequenced using an alphabetic upper and lower case key or sorted based on the content of an alphabetic upper and lower case field may be presented in a different sequence. Note: it is possible to do a case insensitve sort using the ALTSEQ statement of the sort program on the mainframe or with Micro Focus. Refer to the sample sort program provided on the SimoTime Web site. |
||||||||||
| 10. | The technique of comparing the units position of signed, zoned-decimal numbers for an "A-I" for positive values, a "J-R" for negative values and the right and left curly brace for zero that works in an EBCDIC environment may fail in an ASCII
environment. Note: Signed, zoned-decimal format may present some challenges depending on the coding techniques to prepare for printing or exporting. Refer to the zoned-decimal numeric format provided on the SimoTime Web site. |
The preceding is a quick summary of some of the items that are encountered when changing from an EBCDIC-encoded environment to an ASCII encoded environment.
Doing this level of conversion will require the standard unit testing, application testing and system testing before deploying to a production environment. It is important to note that when doing data file compares to validate the results between a Mainframe (EBCDIC) process and a Window, Micro Focus (ASCII) process extra consideration will be required for both the differences in the encoding formats and collating sequences.
Think about this senario. A customer master file contains a twelve (12) byte key. If the first byte of the key is a number then it is an indivudual account. If the first byte of the key is a letter then it is a commercial account. If a program does a test as follows then the logic will work in an EBCDIC-encoded environment but fail in an ASCII-encoded environment.
If CUSTOMER-KEY(1:1) is equal to or greater than 0
ACCOUNT-TYPE = INDIVIDUAL
else
ACCOUNT-TYPE = COMERCIAL
end-if
For the ASCII-encoded environment the preceding code example would conclude that all the accounts are individual accounts. The code would need to be changed to the following.
If CUSTOMER-KEY(1:1) is equal to or greater than 0
and CUSTOMER-KEY(1:1) is equal to or less than 9
ACCOUNT-TYPE = INDIVIDUAL
else
ACCOUNT-TYPE = COMERCIAL
end-if PRE>
The preceding code example would work in both the EBCDIC-encoded and ASCII-encoded environments.
Think about the following senario. A sequential file contains records that will be loaded into a table. The records are in sequence based on the content of an alpha-numeric field. The records in the file are used to load a table in a COBOL (or other language) program. The table is then accessed using a binary search routine. On the new platform we are now working in an ASCII-encoded environment. The original file was EBCDIC-encoded and in sequence by the EBCDIC collating sequence. If we simple convert the file to ASCII-encoded format it will still be in sequence by EBCDIC (or out of sequence in the ASCII-encoded environment). This will cause the binary search to fail. The file must be sorted after the EBCDIC to ASCII conversion (especially since the information in the records is aplha-numeric).
Note: Remember, a SEARCH ALL of a table in COBOL does a binary search and will most likely fail when accessing an ASCII-encoded table that is in EBCDIC collating sequence and contains alpha-numeric data. A SEARCH does a scan of the table starting at the first element and will work but will be much slower for large tables.
This sample suite of programs has one CMD member that executes multiple job steps to sort and present data in the ASCII collating sequence. A subsequent step will then test the characters to determine if they are valid, printable characters. The CMD member will execute a COBOL program that will produce correct results in an EBCDIC environment but will fail in the ASCII environment.
The following is the CMD required to run the demonstration program on a Personal Computer with Micro Focus Net Express.

This sample suite of programs has one JCL member that executes multiple job steps to sort and present data in the EBCDIC collating sequence. A subsequent step will then test the characters to determine if they are valid, printable characters. The JCL member will execute a COBOL program that will produce correct results in an EBCDIC environment but will fail in the ASCII environment.

The purpose of this document is to assist as a tutorial for new programmers or as a quick reference for experienced programmers. This suite of sample programs describes the ASCII and EBCDIC sorting or collating sequences and provides an example of programming logic that will work in an EBCDIC environment (i.e. mainframe) but fail in an ASCII environment (i.e. PC with Windows or Unix). The COBOL programs were written using the COBOL/390 dialect and will execute on an IBM Mainframe or the platforms supported by Micro Focus COBOL (i.e. Windows and UNIX).
