Top Forums Shell Programming and Scripting how to convert data from ASCII to Packed Decimal Post 302316490 by methyl on Friday 15th of May 2009 09:24:04 AM

This would be very difficult in shell but easy in a high level language such as Cobol (pic COMP-3).
Common sense says do the conversion on the Mainframe unless you have the tools on the unix server.
There is much variation in Packed Decimal which is further complicated if you need to generate EBCDIC on the unix server.

If it is really necessary to do the conversion on the unix server the blunt approach is with a conversion table, though you don't state data volumes or anything about the computers or software involved.

NAME
Intro_jfp, intro_jfp - introduction to JFP file formats DESCRIPTION
This section outlines the formats of JFP various files. The C structure declarations for the file formats are given where applicable. Usu- ally, the headers containing these structure declarations can be found in the directories /usr/include or /usr/include/sys. For inclusion in C language programs, however, the syntax #include <filename.h> or #include <sys/filename.h> should be used. Because the operating system now allows the existence of multiple file system types, there are several instances of multiple manual pages with the same name. These pages all display the name of the FSType to which they pertain, in the form name_fstype at the top of the page. For example, fs_ufs. LIST OF FILES
