header option *SRCSTMT may not be what you expect

["Peter Dow" <maillist@xxxxxxxxxxxxxxx>]

Hi Everyone,

Ever since the header option *SRCSTMT was available I've been using it with
the warm fuzzy feeling that as the RPGLE manual states:

"| If *SRCSTMT is specified, statement numbers for the listing are generated
 | from the source ID and SEU sequence numbers as follows:

 |   stmt_num = source_ID * 1000000 + source_SEU_sequence_number"

As it turns out, this is not quite what I expected.  I was assuming that
"source_SEU_sequence_number" referred to the SRCSEQ field in the source
file, but in fact it's the statement number count as the compiler goes
through the source.

I discovered this when I was trying to debug a program with the
aforementioned header, and the debug source statement #'s did not match the
source member I was looking at.  After checking the source date, time and
source file, I finally noticed that the previous programmer had not
resequenced the source member after removing a couple of statements.

Still lots of fun things to learn...
