File Handling Code Examples

>COBOL Coding for Files Example
The general format of COBOL input-output coding is shown. 

>COBOL File Status Code with Text Information
This COBOL file status example will show how to convert the two byte file status code that may contain binary data to a four byte numeric value that may be displayed. 

>COBOL File System and Programming
Here are COBOL file system and programming source code examples. 

>COBOL Record Format Examples
COBOL sample code describing record description, determining fixed-length record size, determining fixed-length record size for files with multiple record descriptions, creating variable-length records with the DEPENDING ON Phrase, creating variable-length records with the RECORD VARYING Phrase, and creating variable-length records and using the OCCURS Clause with the DEPENDING ON Phrase. 

>Comma delimited, QSAM, and COBOL VSAM Files
Here are several COBOL data access sample programs that cover handling comma delimited, QSAM, and COBOL VSAM files. 

>Displaying Record-Lock Messages
This iSeries COBOL subroutine displays record-lock messages. 

This COBOL program converts EBCDIC-sequential to ASCII-indexed. 

>Line Sequential File Example
This COBOL sample demonstrates line sequential file handling. 

>Read an IFS File
This is an iSeries Cobol example showing how to read lines from an IFS file. 

>COBOL VSAM and QSAM COBOL File Status Keys/Error Codes
This is a COBOL program example of how to determine the COBOL VSAM and QSAM COBOL file status keys/error codes in an IBM Enterprise COBOL environment. 

>VSAM File Access for COBOL
If you are interested in writing COBOL programs that utilize VSAM datasets, I hope this documentation has provided you with the information you need to install my routine and get started writing programs on your own.
