* CALLING PROTOCOL
* ----------------
* call 'SIMOPARS' using PRS-PARAMETERS
*
* 01 PRS-PARAMETERS.
* 05 PRS-REQUEST PIC X VALUE '0'.
* 05 PRS-STATUS PIC 9(4).
* 05 PRS-DELIMITER PIC X VALUE SPACE.
* 05 PRS-KEEP-NULL-FIELDS PIC X VALUE 'N'.
* 05 PRS-SUSPEND PIC X VALUE 'N'.
* 05 PRS-SUSPEND-BYTE PIC X VALUE SPACE.
* 05 PRS-TERMINATOR PIC X VALUE 'N'.
* 05 PRS-TERMINATOR-BYTE PIC X VALUE SPACE.
* 05 PRS-BUFFER-SIZE PIC 9(4) VALUE 2048.
* 05 PRS-BUFFER PIC X(2048).
* 05 PRS-TABLE-MAX PIC 9(4) VALUE 128.
* 05 PRS-NUMBER-OF-ITEMS PIC 9(4) VALUE 0.
* 05 PRS-LAST-SIG-BYTE PIC 9(4) VALUE 0.
* 05 PRS-POSITION OCCURS 128 TIMES
* PIC 9(4) VALUE 0.
* 05 PRS-SIZE OCCURS 128 TIMES
*
* This routine uses reference modification to identify the
* position of the first significant character after the
* delimiter character. This approach compensates for multiple
* leading or embedded delimiter characters. The string function
* of COBOL does not handle leading spaces.
*
* For example, if the delimiter character is a space then
* leading spaces will be ignored and multiple, embedded spaces
* will be treated as a single space.

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. SimoZAPScan 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.
This item will provide a link to an ASCII or EBCDIC translation table. A column for decimal, hexadecimal and binary is also included.
This document provides a quick summary of the File Status Key for VSAM data sets and QSAM files.
