> AMODE 64 code will run slower than AMODE 31 code Really? Because the compile will generate extra instructions or similar, or inherently because of the hardware architecture?
I thought there was some discussion here recently that dismissed the latter (other than a trivial factor).

Best regardsManshadi AMODE 64 COBOL is still being worked on here at IBM. I (like the other poster) would like to know what you would do with AMODE 64 COBOL? Also, does everyone realize that AMODE 64 code will run slower than AMODE 31 code? We assume that AMODE 64 COBOL will be used for very specialized one-off cases to solve specific business problems, and that in general 99% of code will be compiled for ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
