The object module produced by High Level Assembler is portable across all the supported operating systems (but GOFF object files are not portable to z/VSE). Therefore, an assembler program may be assembled under any of the supported operating systems and run under any of the supported operating systems. For example, an assembler program may be assembled under CMS and run under z/VSE if the appropriate macro libraries are used for assembling the program.
The object module is portable across the supported operating systems with the following restrictions:
The z/VSE linkage editor, prior to VSE/ESA Version 2 Release 1, does not support dummy external DSECTS. Therefore, to link-edit the assembler program under earlier VSE operating systems, the assembler program must not include any DXD or CXD statements or Q-type address constants.
The TEST option cannot be specified with the GOFF assembler option, which produces the generalized object format module.
