Introduction
(Next) (Previous) (Table-of-Contents)

This suite of programs provides an example of various routines that edit, validate, fomat or convert dates. Two COBOL programs are provided. The first program is a demonstration program that reads a file containing "date-card" records and calls the second COBOL program that actually does the date validation, formatting and conversion.

Both 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 is provided in the Downloads and Links to Similar Pages section of this document.

Programming Objectives
(Next) (Previous) (Table-of-Contents)

The following is a list of the functions provided in this example.

1. Accept Gregorian date as input.
2. Validate the month for 1-12 and create text string (i.e. month 7 is July).
3. Determine if the year is a leap year.
4. Vaildate the day for 1-30, 1-31, 1-28 or 1-29 based on month and leap year.
5. Create a text string for the date (i.e. 2002/01/01 is January 1, 2002)
6. Create a ccyyddd format for the date (i.e. 2002/04/01 is 2002092)
7. Calculate days remaining in the year.
8. Provide an edited Gregorian Date (I.e. 20020915 could be 2002-09-15)

Programming Input and Output

The Call Interface
(Next) (Previous) (Table-of-Contents)

The following is the syntax for calling the date routine (SIMODATE.CBL).

        call 'SIMODATE' using STD-SIMODATE

The callable date routine will accept a gregorian date and provide a data structure in the following format. A copy file (PASSDATE.CPY) is provided with the following fields defined.

The following table is an overview of the data strings used in the pass area.

Field Name Description
STD-REQUEST This is an eight character data string and should contain the following in upper case.
EDITDATE This keyword causes the date routine (SIMODATE) to validate the date and provide and edited text string plus a julian date and more.
This calling program must provide one of the above as a request. Otherwise, a non-zero return code will be set in the following result field. This data string is not changed by the conversion routine.
STD-RESPONSE This is a four byte binary data string and is used by the conversion routine to pass a return code. If the conversion request is successful the value in this data string will be zero.
STD-MESSAGE-TEXT If a non-zero response occurs this field will contain a short message.
STD-GREGORIAN-4-EDIT

This is the input date field in gregorian format that will be vaidated. If the gregorian date does not pass the editing process a message will be posted in the STD-MESSAGE-TEXT field and a non-zero value of 16 will be placed in the STD-RESPONSE field. SimoDATE is somewhat flexible in accepting and reformatting a gregorian date. For example, the following are acceptable and will be reformatted into the STD-GREGORIAN-4-EDIT field.

ccyymmdd   This is the preferred format.
ccyy-mm-dd    Special characters may be used as separators.
ccyy-m-d   Single digit month and day values are acceptable when separators are used.
ccyy/m/dd   A mixing of single digit usage is accepted.
STD-DEBUG-INFO This data string provides additional debugging capability. This may be helpful if changes are made to the date routine..
STD-LEAP-YEAR-YN This field is used to identify a leap year. A "Y" indicates the input date is a leap year. An "N" indicates the input year is not a leap year.
STD-MONTH-VERBAGE This field is used for the text of the input month. For example, 1=January, 2=February, etc.
STD-MM-DAYS This field is used for the number of days in the input month.
STD-GREGORIAN-DATE This field is used for the gregorian date in ccyymmdd format (all numeric values).
STD-JULIAN-DATE This field is used for the julian date in ccyyddd format.
STD-DAYS-REMAINING The number of days remaining in the year.
STD-DATE-VERBAGE This field is used for the date in text format. For example, 19991225 will produce a text string of December 25, 1999.
STD-DATE-EDIT-BYTE This field contains the character that will be used to edit and format the gregorian date. For example, this field may contain a space, a dash, a slash, etc... and will be used as the delimiter between the year, month and day.
STD-DATE-EDITED This field if for the edited date using the delimiter character from the preceding field. For example, 19991225 will produce 1999/12/25 if the delimiter character is a slash.
