@ pc68909
Are you someone of thesse developers, programming, designing and implementating high performance authorized routines. SRB and cross memory mode ???
Then you'll need to know about MVCSK & MVCDK !!!
Otherwise ??? |

If (by chance) you're writing what UmeySan has said, Google ===> "advanced assembler language and mvs interfaces". You'll find a book with this title (out of print) but commands some serious bucks, even when used!
When it was in print, it cost $80.00 and that was 6-8 years ago.

Hello,

Suggest you not try to re-code the assembler instruction-for-instruction in cobol. . . Re-write the functionality - if possible, but not the specific lines of code.

Depending on just what the assembler module(s) accomplish, you may not be able completely replace them in cobol.
While learning assembler is valuable, i believe understanding the scope of this "re-write" may be more immediate. Suggest you itemize what this code accomplishes and deterine if this can be written in cobol. fwiw. . . |

Hello Bill O'Boyle
Thnx for the help provided by u......
YA ...it wont be 100% automated .some manual tasks will be left in cobol equivalent.I am trying to learn the instructions first ...I agree that all instructions dont have direct cobol equivalent.So by understanding the instructions corresponding logic for that have to be developed in cobol.... |

Dear Sir !
As i had given advice to some projects dealing about assembler conversations to Cobol, i allways realized the leading thought about a
automatic code conversation.
Plse Sir, vorget about such pipe dreams. I saw several Tool and i saw the
resulting code of such tools. The further maintenance of such code would be extremely time-consuming.
The very best way is, to do what Dick already mentioned: no re-coding,
re-writing the functionality. So you also have the chance to re-engineer the Programm and include new technologies that are up to date now.
I know, this is not always that, what the consultancy market prefers.
To much work, low yield, also longer project timeline. And all these jabbering about the divine and high technologie converters, i really could not hear it anymore whitout a a queasy feeling.
Good luck with your project. |
