SAS/C Software: Changes and Enhancements, Release 6.50

Search Lists

This release of the SAS/C Debugger enhances the set search capability introduced in Release 6.00. In Release 6.00, only one attempt to locate the debugger or source files would be made. This meant that if the set search commands located in the profile were not correct, or had not been corrected before an attempt to load the source, the current debugging session would have to continue without access to that particular source.

In Release 6.50, that behavior has been modified, such that, if a set search is issued, followed by a list command, then the degugger will attempt to load any files that were not previously found, using the modified set search templates. For example, if an attempt to load a source file failed because the source files had been moved to the dataset SASC.APPL.SOURCE, then issuing the command :

set search source+"dsn:sasc.appl.source(%basename)"

followed by a list command would cause the debugger to reattempt the search for the source.

Note that the set search issued does not have to directly correlate to the failed search. For example, a common problem encountered when debugging, is to forget to allocate the DBGLIB dataset definition. When the debugger fails to locate the debugger file, a command such as:

system alloc fi(dglib) dsn(appl.dbglib)shr

could be issued to allocate the DD. A 'dummy' set search command could then be issued. For example:

set search altsource+""

followed by a list command will cause the search to be reattempted.
