The command-line option AltLog saves a copy of the SAS log.

It works like the option log.

This statement produces an explanation of the option.

proc options define value option = altlog;

The argument can be either:

  • directory specification
  • file specification

Usage with directory specification: creates ..\altlog\MyProgram.log:

sas MyProgram -altlog ..\altlog

Usage with file specification: creates MyProgram1.log and MyProgram2.log

call sas MyProgram -altlog MyProgram1.log
call sas MyProgram -altlog MyProgram2.log
