I taught myself IBM DOS/VS Assembler using the famous "Sharon K Tuggle" book and a whole IBM 370 to myself ;-) We didn't have energy problems back then. That book has a whole section on saving

Fish, Tom,Actually this one is closer to the age of DOS/VS R 34 than the 3rd

Thank you for the book reference. I am going to see if I an find it,as I am trying to learn DOS/VS asm. /cheers /tom c

Tom,Peter Abel authored a book called, Programming Assembler Language (not to be confused with his book for PC Assembler) that covers what you are looking to do.? The book is primarily oriented

Thank you to all who responded.? Each response gave me more information. I now can nest up to 4 levels and I have getting the results that I expect. I removed the SAVE and RETURN, replaced with

It was a zip file in the OLD DOS/VS files area. That was the name of the file. along with a file that had $b transits also. I guessed it was you, but could be wrong. Sorry /cheers tom c.

Not only that, but DOS/VS r 34 didnt follow the OS calling conventions. Joe wrote:

ok, maybe a little progress. Knowing that standard calls do not work, as you state, means that I have to do my own. Ok, now for some testing..... Thank You very much. cheers /tom c wrote:

Hi Tom, You are going to have to implement your own routines. Perhaps check out how Algol or PL/1 handle subroutine calls. But standard call routines do not support re-entrant calls. Rich

Richard, Thank you for the info. I need to figure out how to implement your suggestion. I found in the documentation on SAVE an option SAVE (14,12),,xxxxxxx where xxxx is a ds 18f area

Hi Tom, Typically 360/370 subroutine calls are done with a what is called a save area. This is 18 words allocated within the subroutine. On entry the registers are saved into the previous

Fish, Thank you for comments.? You confirmed what I thought was the issue. Looking through the fish-macros, I noticed you have a modified save macro.? Should I be using that version? I have written

Fran Hensler wrote a routine, EchoParm, which allows for the use of EXEC PARM= . The program compiles but will not run via DOS/VS rel 34.? It is stated in the JCL: Restriction:? This program will
