Dataspaces and Hiperspaces came out in the 1988-1989 timeframe. COBOL has never supported them, yet COBOL has been able to interface successfully with DB2 for that entire time, despite the fact that DB2 has exploited dataspaces and hiperspaces for years. I will admit that it is quite likely that a need for 64 bit support in COBOL is coming down the road, but I don't have a clue how far down the road. Be aware that IF IBM every does support 64 bit COBOL, it will be under the LE umbrella, which, for 64 bit C, C++ or LE conforming assembler means:
The only means of communication between AMODE 64 and AMODE 24 or AMODE 31 applications is through mechanisms that can communicate across processes or address spaces. However, Language Environment applications that use AMODE 64 can run with existing applications that use AMODE 24 or AMODE 31 on the same physical zSeries system. Basically, your entire application will need to be recompiled, retested, etc. to support 64bit support, or else they will need to use some sort of IPC model to communicate from a 31 bit application to a 64 bit application (such as sockets). Going to 64bit will NOT be a panacea that some seem to believe.

We will need 64 bit support in COBOL on day one of the time that it could be used. Then is NOT the time to decide whether there is a need for it. COBOL needs to be able to play efficiently with things like XML and the above listed subsystems. If they don't use 64 bit, then COBOL doesn't need it. If they do and interface with 64 bit application code, COBOL needs 64 bit capability. In this sense, if IBM internal communications are adequate, IBM has a better idea of the need and the time frame for the need than the customer base. We as customers should be almost yelling at IBM that we don't want to have to rewrite code just so that we can use it efficiently with JAVA, Websphere or any other offering. > ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
