This is an example of how COBOL can do case conversion of alpha-numeric data within a field (or text string). The four basic functions provided are as follows.
| 0. | Convert a text string to lower case. | |
| 1. | Convert a text string to upper case. | |
| 2. | Capitalize each word in a text string. | |
| 3. | Edit specific words in a text string using pre-defined table values. |
This is an example of how COBOL programs do case conversion. The example shows simple conversion between upper and lower case plus capitalization and editing of specific words within a text string. Both COBOL programs were written and tested using the VS COBOL II dialect. Also, both COBOL programs will 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 (refer to http://www.microfocus.com ). Also, a CMD member is provided to run the job with Micro Focus Net Express (MFE) running on a PC with Windows.
In the world of programming there are many ways to solve a problem. This suite of programs is provided as a COBOL programming example of one of the possible solutions for doing case conversion of alpha-numeric text strings. This example may serve as a tutorial for new programmers and as a reference for experienced programmers. Additional information is provided in the Downloads and Links to Similar Pages section of this document.
Note: The source code for this example is available from the SimoTime Library under Download Directory at www.simotime.com
The callable interface requires a data structure to be defined. A copy file (PASSCASE.CPY) is provided with the following source code.

The input text string is moved to CASE-PASS-BUFFER before the call to SIMOCASE. After returning from the call with the CASE-PASS-REQUEST set to a value of '0' or ZERO a lower case text string will be returned in CASE-PASS-BUFFER.
| Input | THE QUICK BROWN FOX JUMPED OVER THE LAZY DOG'S BACK | |
| Output | the quick brown fox jumped over the lazy dog's back | |
Example |
move '0' to CASE-PASS-REQUEST call 'SIMOCASE' using CASE-PASS-AREA |
|
The input text string is moved to CASE-PASS-BUFFER before the call to SIMOCASE. After returning from the call with the CASE-PASS-REQUEST set to a value of '2' a lower case text string with each word capitalized will be returned in CASE-PASS-BUFFER.
| Input | the quick brown fox jumped over the lazy dog's back | |
| Output | The Quick Brown Fox Jumped Over The Lazy Dog's Back | |
Example |
move '2' to CASE-PASS-REQUEST call 'SIMOCASE' using CASE-PASS-AREA |
|
The input text string is moved to CASE-PASS-BUFFER before the call to SIMOCASE. After returning from the call with the CASE-PASS-REQUEST set to a value of '3' a lower case text string with each word capitalized and specific words modified based on an internal table will be returned in CASE-PASS-BUFFER. Notice in the following example the second occurence of "the" is not capitalized.
| Input | The Quick Brown Fox Jumped Over The Lazy Dog's Back | |
| Output | The Quick Brown Fox Jumped Over the Lazy Dog's Back | |
Example |
move '3' to CASE-PASS-REQUEST call 'SIMOCASE' using CASE-PASS-AREA |

There are two (2) Windows Command files provided with this suite of sample programs. The first Command file will execute the sampe programs that do the actual case conversions.
The second Command file is used to create a file that contains records with text strings that will be converted by the case conversion sample programs. This Command file should be executed at least once prior to attempting to execute the sample programs.
The following is the Windows Command file (CASECRE1.CMD) that is required to run as a job on a PC using Micro Focus Net Express.

This program (SIMOCASE.CBL) was originally written to be used as a teaching and learning aid. It was first used in a production environment to replace a callable 370 assembler routine. Today, this program (or a modified version) is used in a number of mainframe shops and it is the program of choice used by SimoTime. Also, the program has been tested and deployed on the PC with Mainframe Express or Net Express from Micro Focus. The source code for the SIMOCASE callable program. is part of the SimoMODS package of callable routines.
This copy file (PASSCASE.CPY) provides a convenient method for defining the data areas (or fields) that are used to pass information between the demo program and the case conversion routine.

The SimoZAPS Utility Program has the capability of generating a COBOL program that will do the conversion of sequential and VSAM (KSDS) files between EBCDIC and ASCII. SimoZAPS can also read a sequential file in EBCDIC format and create an ASCII/CRLF file or VSAM KSDS file in ASCII format. The conversion tables may be viewed or modified to meet unique requirements. The Hexcess/2 function provides the capability of viewing, finding or patching the contents of a file in hexadecimal.
