I have contacted Frank and this is what Frank told me:
The -g option of vbcc only provides HUNK_SYMBOL (global
symbols) and HUNK_DEBUG with LINE-debug entries. Other debug hunks are not
documented and SAS/C specific.
No information about local variables, types or structures are provided by
He can make it work with cpr only if there is info about sas/c hunk format so it will be dificult
to have support.
