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:

Hope this helps,

Tendulkar,

Thank you for your reply. It's very useful for me. Do you play cricket?

We have one Sachin TENDULKAR to shine INDIA worldwide....
Here we have one Mayuresh TENDULKAR to popularize ibmmainframes.com worldwide

Am I right?

Why not we teach Mainframes to sachin ?

I disagree with the comment that the compilers require LE.

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.

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.
