IBM MAINFRAME: Possible to do recursion..

    http://ibmmainframes.com/about5185.html
    Its possible to do recursion in COBOL. Here is the example to do so. Cobol also has stack concept but this is object oriented cobol, one can even write methods and classes. I believe there are better ways to write a recursive program than the one below. Below one is just an example for the concept. ID DIVISION. PROGRAM-ID RECURSVE RECURSIVE.

Are there any modern languages not supporting recursion ...

    https://stackoverflow.com/questions/53318154/are-there-any-modern-languages-not-supporting-recursion
    I know COBOL doesn't (or didn't) support recursion and I imagine it's the same for FORTRAN (or at the very least they will have a weird behaviour), but are there any modern languages? There are several reasons I am wondering about this...

    Feb 29, 2008 · Re: Recursion In Cobol by pi17388 » Fri Feb 29, 2008 1:28 am depending on the specific language environment/runtime libraries in use (OS/VS Cobol; VS Cobol II, IBM Cobol; Enterprise Cobol) you will need to use compiler options (RENT and REUS).

What imperative programming languages do not support ...

    https://softwareengineering.stackexchange.com/questions/21300/what-imperative-programming-languages-do-not-support-recursion
    The OpenCL programming language does not support recursion. (see section 6.8 of the OpenCL Spec ) The current motivation for that is a) a lack of space for deep stacks b) a desire to know, statically, the total required allocations in order to optimize for performance in the presence of large register sets and extensive in-lining.

Using Recursive Calls - IBM

    https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/rzase/recursvcal.htm
    Using Recursive Calls Code the RECURSIVE clause on the PROGRAM-ID clause so your program can be recursively reentered while a previous invocation is still active. Below is an example of how you could use the RECURSIVE clause to make a program a recursive program, and how a Local-Storage Section data item can be used in a recursive program.

IBM MAINFRAME: Can we use perform in perform statement

    http://ibmmainframes.com/about48817.html
    May 18, 2010 · Enterprise COBOL brought RECURSIVE to COBOL on IBM. The reason PERFORM is not suitable for RECURSIVE programming, is as you said - concept of stack (multiple returns) and data integrity, that a PERFORM can not invoke anything that could establish an environment that would support the implementation of RECURSIVE.
