RE: STRDBG Max size of program.

What I found was that the program had a Copy Book that had *SRCSTMT and 
according to the help text which was 

"Note:  When OPTION(*SRCSTMT) is specified, all 
sequence numbers in the source files must contain 
valid numeric values. If there are duplicate 
sequence numbers in the same source file, the 
behavior of the debugger may be unpredictable and 
statement numbers for diagnostic messages or cross 
reference entries may not be meaningful.           "

When looking at the following 

  1  000100030804 
  2  000200030804 
  3  000300030807 
  4  000400030807     What ever code etc.
  5  000500030804 
  6  000600030804 
  7  000700030804 
  8  000800030804 
  9  000900030804 
 

Note what happened here:

9999     999900030804 
10000  999999999999
10001  999999999999

Any break point set after 10000 when to last statement in program.

As soon as I removed *SRCSTMT and re - sequenced and added back *SRCSTMT 
STRDBG  OK.

Thanks
