Set Command [S]
Enables or disables certain operating options within Suprlink. These options are not reset by Xeq or Reset commands.
SET [MAPPED ON|OFF]
[REDO filename]
[STATISTICS ON|OFF]
[VARSUB ON|OFF]
[VARSUBDEBUG ON|OFF]
Mapped
SET MAPPED ON | OFF
(Initially: OFF)
MAPPED forces Suprlink/iX to read the input and link files using mapped file access. Specifying this option is an error in Suprlink/V. If the input and link files are not in memory, the wall time performance is worse with Set Mapped On, but CPU time performance is better. You must Set Mapped On before specifying the input file.
Redo
SET REDO filename
(Initially: unnamed temporary file)
Commands entered at the Suprlink prompt are saved in something called the redo stack. You can recall commands from the redo stack by using other commands such as Before, Do and Redo. By default, the redo stack is stored in a temporary file and discarded as soon as you exit. This temporary stack is not preserved across Suprlink invocations.
The new Set Redo command assigns a permanent file as the redo stack, allowing the stack to become available for future Suprlink invocations. For example, to assign the
Myredo file as a persistent redo stack, enter
+set redo myredo
If the file does not exist, Suprlink creates it. Otherwise, Suprlink uses the existing file. All subsequent commands are written to the persistent redo stack. The setting is valid for the duration of the Suprlink session. As soon as you exit Suprlink, the setting is discarded. Next time you run Suprlink, you will get the temporary stack.
If the file name is not qualified, the redo stack is created in the logon group and account. This may be desirable if you want to have separate stacks. If you want to always use the same persistent stacks, you should qualify the name.
The Verify command shows which stack is currently in use. If it shows
<temporary>, it means Suprlink is using the default stack. Anything else is the name of the file used on the Set Redo command.
