SASDump - SnapDump Processor


SASDump is a Dump processor for SnapDumps produced by z/OS Products built using the SAS/C® Compiler System.

Why is it required?

In a word - "timesaving", for both Developers and Level3 personnel.

On z/OS, external names, i.e. names of C/C++ Functions, can only be a maximum of 8 uppercase characters. Therefore, if someone calls a function in a program getSourceFileName() it is obviously too long and contains lowercase characters.

So, the SAS/C® Pre-linker will hash these function names, and other external names, into a six digit number preceded by an '@' character, therefore "getSourceFileName" may become @@342396 This is obviously internal to the SAS/C® Compiler System, and we would not normally need to know about it.

Unfortunately, when a module built with SAS/C® crashes, all we have to go on to find where is a list of these @@ numbers, which look like this;
