The SimoDATE routine (or callable program) will validate, edit and convert a given date in the ccyymmdd format into various other formats. For example, if the date of 20000401 (or April 1, 2000) is pased to the SimoDATE routine the following will be returned in the pass area.
Gregorian Date .............. 20000401 Edited Gregorian Date ....... 2000-04-01 Text for the Date............ April 1, 2000 Julian Date ................. 2000092 Days remaining in the year .. 274 Leap Year Flag (Y or N) ..... Y Days in the Month ........... 30 Text for the Month .......... April
The following will validate, edit and convert the date of April 4, 2000.
MOVE X'EDITDATE' to STD-REQUEST
MOVE '20000401' to STD-GREGORIAN-4-EDIT
CALL 'SIMODATE' using STD-SIMODATE
A copy file is provided to define the pass area to be used when calling SimoDATE. The following statement is required in the WORKING STORAGE section of the calling program.

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.
