Thanks every body for your ussefull apointments. I have opened this topic because it was a surprise for me. No other problems and considerations are involved. Each language is different from others and each person or company will choose one depending on their needs. Mi client ask me to developp program in two languages concerned because their primary use will be massive in a highly loaded teleprocessing environment.
Some notes to clarify terms - Magnitude (Miklos asked): DOUBLE CPU used by ASSM program. - ASSM and COBOL have the same mainline execution in a batch scenario: it receives a parameter from a calling program, it does a lot ot of mathemathic operations and call many times to CSF for crytographic purposes. After that, it returns control to calling program with a result. There a lot of cross-memory services involved, but are the same for ASSM or for COBOL. - RENT in assembler is coded based in a workarea receveid from calling program. No STORAGE OBTAIN, GETMAIN or FREEMAIN a re used. - Assembler program is LE conforming. As a personal challenge, apart from professional needings, i will try to improve performance of assembler program as a means to improve my skills. I wrote mi first assembler program in 1972 but "world is changing every minute" and it is neccesary to learn new things every day. Thank you all for your knowledge and your time. angel luis dominguez z/os system programmer - spain
