Assembler programs cannot call or use directly CELQSTRT, CELQMAIN, or CELQFMAN as a standard entry point. Results are unpredictable if this rule is violated.

When binding an AMODE 64 application, it must be possible for the binder to resolve CELQSTRT. As long as the NCAL bindor option is not specified, CELQSTRT is automatically resolved. If NCAL is used, it becomes necessary to explicitly include CELQSTRT in the bind process.

The main entry point for an AMODE 64 application is CELQSTRT. On the assembler END instruction, do not specify anything other than CELQSTRT as the point to which control can be transferred after the program is loaded.
