Some functions are different in SAT. Three MODIFY commands are enabled
for SAT, and the FPMAP and EXIT commands are changed. SAT is
a standalone environment, so the file system is not available. This means that
no operation which involves the file system, such as USE files, List or Log
files is allowed.
For standard functions nmaddr and nmfile, only addresses
contained in the system library succeed. For standard function strmax,
strings are limited to 1024 characters.
There are no additional commands for SAT, but three DEBUG MODIFY
commands have been enabled for it so that repairs may be made to the machine
state, system tables or other data structures. These commands are summarized
below. For more information, see the M (MODIFY) command
description in Chapter 4.
MV
modifies a virtual address
MZ
modifies a real address
MSEC
modifies addresses in secondary (disk drive) storage
NOTE: Take care when using these commands; modifications can be
permanent, such as disk changes.
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. Only SL.PUB.SYS CM
symbols are accessible, so FPMAP alone (no parameters) is sufficient.
The exit and c[ontinue] commands return control to ISL.
However, the exit command has two additional parameters, as shown in
the following syntax example:
EXIT [ISL_Command] [,ABORT]
Parameters:
ISL_Command
Allows you to directly pass a command to ISL. For example, enter the
following to tell ISL to load the START PME:
exit start.
ABORT
This option tells ISL to abort the AUTOBOOT sequence if it is
enabled.
