The Question is: MACRO on ITANIUM? 1) Will my MACRO programs run on ITANIUM? 2) Will I still be able to modify and assemble them? 2) Must I rewrite them (in C)? Thanks. The Answer is : A VAX Macro32 compiler is available on OpenVMS I64, analogous to the availablity of a VAX Macro32 compiler on OpenVMS Alpha. As is discussed in the FAQ, a substantial portion of OpenVMS remains written in VAX Macro32 assembler. The OpenVMS Wizard would strongly encourage a review of the porting documentation, as you start to look at porting your source code to OpenVMS I64. The documentation expected to be provided with V8.2 does include information specifically around porting source code. The documentation does identify sepcific areas of interest when porting source code, and identifies options and requirements. As for whether or not your particular code is portable to OpenVMS I64, that depends highly on the code itself, and particularly on what architectural features the code might use. As was recommended with ports from VAX to Alpha, a review of such code is encouraged -- much has changed since most VAX Macro assembler code was written. There may well be a direct or easy replacement, given the additional system services and run-time library services that have been added. As was the case with porting from VAX to Alpha, the vast majority of application source code is expected to require little more than a full source rebuild.
