Convert EBCDIC and ASCII  SimoXT80 - a Called Routine for Eighty-Byte Text Strings

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

This document provides a listing of the COBOL source code for a callable routine that provides conversion between ASCII and EBCDIC for an eighty (80) byte text string. This program is included in the SimoCARD suite of programs.

How to Use
(Next) (Previous) (Table-of-Contents)

The SimoXT80 program provides an easy to use, callable routine for converting an eighty (80) byte string of text data between ASCII and EBCDIC.

First, the pass area (or data structure) must be defined in the WORKING-STORAGE section of the program that will call SIMOXT80. A COBOL copy file is provided for this purpose and the same copy file is used in the LINKAGE section of SIMOXT80.

       COPY PASSXT80.

Next, the data items in the pass area need to be initialized prior to calling SIMOXT80.

           move 'A2E ' to XT80-REQUEST  
           move 'Test Data' to XT80-DATA

Next, the following shows the line of code that makes the call to SIMOXT80.

           call 'SIMOXT80' using XT80-PASS-AREA

The following is a list of the parameters required when using the XT80-PASS-AREA to call the SimoXT80 routine.

Note:  A listing of the COBOL copy file is provided in a following section of this document.
