Hello priya,

There are a number of IBM COBOL compilers that require the LE run-time
library. The names of the products (on MVS, OS/390, and z/OS) that require LE are:

IBM SAA AD/Cycle COBOL/370
IBM COBOL for MVS & VM
IBM COBOL for OS/390 & VM
IBM Enterprise COBOL

Following are the links to study more about the LE:

Migration Guide

COBOL LE Conversion Guide

LE Run-Time Migration Guide


Hope this helps,

Regards

Mayuresh Tendulkar

I disagree with the comment that the compilers require LE. icon_sad.gif

LE was "invented" by IBM to save having a seperate run time enviroment for each langauge. COBOL 2 had the ILB* routines, PL/1 had there routines, etc etc.

LE provided a comon environment that is not cobol compiler specfic. this means that each and every language on the mainframe now has access to one and only one run-time environment. icon_biggrin.gif The compiler produces object code which when link-edited produces run time code and that is where LE is executed.

I agree with xzsymr.
Here is my 2 cents.
Language Environment will creates a single run-time environment for multiple high level languages, like C/C++, COBOL, PL/I etc.
It is available for both OS/390 and VM/ESA.
The advantage of having a single runtime environment are
1. Language specific incompatibilities are eliminated. For example a COBOL application can be easily and effortlessly communicate with a PL/I or C application.
2. There a lot a LE callable service available for date and time services, mathematical function and others. These services can be easily called by all the platforms, since it is common for all applications.
