Date Processing Validate, Format and Convert |

Introduction
This suite of programs provides an example of various routines that edit, validate, format 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 OS390 dialect and also work with Enterprise COBOL. 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.
We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

Programming Requirements
This suite of samples programs will run on the following platforms.
| ||||||
| Program Requirements for the Data Validation Example |
Programming Overview
The following diagram is an overview of how the demonstration program fits into the example. The demonstration program will read the date card file (SYSUT1), call the date routine and write the results to the output file (SYSUT2).

| Overview of the Sample date Validation Process |
The CALL Interface
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.

*****************************************************************
* 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 an edited text string plus
* a julian date and more.
* EDITJDAT, WIP
* The calling program must provide 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 date 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 date 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 validated.
* 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
* delimiter 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.
* STD-DAY-OF-WEEK - WIP, 1-7 is Sunday through Saturday.

The COBOL Programs
This example includes two COBOL programs. The primary program reads a file containing records with a variety of dates in a cccc-mm-dd format. The primary program calls the validation routine to process each date and the edited date information is written to an output file and posted to the SYSOUT device.
The Primary Program
The following (CBLDATC1.cbl) is the source code listing for the demonstration program.

Company Overview
SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.
Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.
Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.
Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
