Permanent I/O error on debug

[daparnin@xxxxxxxxxxxxxx]

Greetings,

I'm trying to debug a display program that uses a subfile.  I do a STRDBG 
with UPDPROD(*yes), set some break points, then when it hits a EXFMT 
statement for a non-subfile display record it gets a permanent I/O error. 
When I run the program outside of debug I don't get that error.  Hitting 
F1 on the message tells me to examine the major and minor return codes. 
The major return code is 80. The minor return code is C0.  That doesn't 
tell me much except that I got a system or file error.  Can anyone offer 
any suggestions on what's causing this only while debugging?  Thanks.
