Display Source List. A subfile approach for looking at source member level
information. The supplied command CPYSRCLST refreshes the file used. CPYSRCLST
should be run on a regular basis. DSPSRCLST allows access by member name or by
library/file/member. The source member names can be scanned as well as the text
when attempting to determine a source member name. Provides a faster solution
than DSPFD member list or PDM.
