SAS/C Software: Changes and Enhancements, Release 6.50

Inclusion of Debugging Information in the Object Deck

In Release 6.50, the compiler allows for the placement of the debugging information in the object file when the dbgobj option is specified. The dbgobj option is specified by default when the autoinst option is enabled. When this information is discovered by COOL to be present in the object file, COOL will write the debugging information to a file supported by the debugger. The default filename used is somewhat different than when the debugging information is written directly by the compiler in that it is generated using the sname of the containing object.

dbglib Option

The dbglib option specifies a debugger file qualifier that provides for customization of the destination of the debugger file.

For each platform, dbglib specifies something different:

ON MVS:

A SAS/C file specification that denotes a PDS. The filename is constructed using whatever is supplied, followed by ( sname).

On CMS:

If the option specified starts with a ' /', then it is assumed that this is either a ' //sf:' file specification or an SFS path. In this case, the specification is prepended to the filename. For example,

 dbglib(//sf:ted/)

will generate the name

 //sf:/ted/sname.DB

If the option specified does not start with a ' /' then it is considered to be a filemode, and will be appended to the filename. For example,

 dbglib(d2)

will generate the name

 sname.db.d2

On OE:

The option specified is a path name to be prepended to the filename. For example,

 dbglib(/u/sasc/dbg/)

will generate a filename of

 /u/sasc/dbg/sname.dbg370

The option has different defaults on the various platforms:

ON MVS:: dbglib(ddn:sysdblib)
On CMS:: dbglib(A)
On OE:: dbglib()

For the various platforms, the default filename has different forms:

On MVS:: ddn:sysdblib(sname)
On CMS:: sname.DB.A
On OE:: hfs:sname.dbg370

Note: On OE and UNIX platforms, the sname is capitalized and remains so for debugger filename generation. [cautend]

The short form of this option is -db.
