dump subprocedures

I have a pgm that consists of one module with a main and another module with 
multiple subprocedures and nomain.  If there is an error in one of these 
subprocedures, and a D or F is taken, the dump doesn't have any of the file or 
variable info.  I found that if I add the DUMP opcode to the subprocedure, that 
I can get all of the variable and file info.

Is this the way that it is?  Or is there a way to get a worthwhile dump?  I 
know I can add a monitor or E extender but then the pgm doesn't halt.  These 
are usually batch jobs and we can't ignore when an error occurs.  I could send 
an inquiry message but first want to see if there's a better way.

Thanks for your input!
