Operating Restrictions

• The symbolic access functions are not available.

• The only symbols that are accessible in CM are the SL.PUB.SYS symbols.

• No operation that involves the file system, such as use files, list, or log files is allowed, since the file system is not available in a standalone environment.

• Some commands and functions are different in SAT:

  • The EXIT and C[ONTINUE] commands return control to ISL. The EXIT command has two additional parameters, ISL_Command and ABORT. An example follows in "SAT Commands" in this chapter.

  • The FPMAP command is automatic and is executed at boot time. When the most recent process is executing in REAL mode, it may be necessary to switch to another PIN and issue the FPMAP command explicitly. Since only SL.PUB.SYS CM symbols are accessible, no parameters are need with FPMAP.

  • For standard functions nmaddr and nmfile, only addresses contained in the system library will succeed.

  • For standard function strmax, SAT strings are limited to 1024 characters.

• The following System Debug commands cannot be used in SAT:
