Does anyone else have a problem debugging programs that use pointers?  
The following is an example.  The structure QZMFMDAE is defined in 
QSYSINC in QZMFASRV.  Note that debug displays the pointer QZMMDP 
differently when I display the data structure.  Displaying the data structure 
in 
hex the pointer is correctly represented.  This happen to us all the time.  
Anyone else have these things happen?  "Variable not available to display", 
etc.  We are on V3R7 with all of the available PTFs.

I tried putting this as both a local and global definition.  Same result.

Reminds me of something I once heard.  "The only bug I ever had was 
when I thought I had a bug and I didn't." 

> EVAL QZMMDP
  QZMMDP = SPP:C0AB6D44EF000210
> EVAL QZMFMDAE
  QZMMDP OF QZMFMDAE = SPP:C0EAD97D4A0009D0
  QZMMDL00 OF QZMFMDAE = 000000316.
  QZMMDFN08 OF QZMFMDAE = 'ORGL0100'
  QZMERVED14 OF QZMFMDAE = 000000000.
