Regarding Compiler Option *SRCSTMT & *NOSRCSTMT on CRTBNDRPG Command

Dear All,

            I tried "zoom in" to these options and got a bit confused
.The F1 key on these fields gives the following definition

  

            

            *NOSRCSTMT


             Line Numbers in the listing are assigned sequentially;
these            

             numbers are used when debugging using statement numbers.
Line          

             Numbers are shown on the left-most column of the listing.
The          

             source IDs and SEU Sequence Numbers are shown on the two
right-most     

             columns of the listing.


 

             *SRCSTMT


              Statement numbers for debugging are generated using SEU
sequence

 numbers and source IDs as follows:                                  

    Statement_Number = source_ID * 1000000 +                        

                       source_SEU_sequence_number                   

 SEU Sequence Numbers are shown on the left-most column of the       

 listing.  Statement Numbers are shown on the right-most column of   

 the listing; these numbers are used when debugging using statement   

 numbers.                                                            

 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.                        

 

 

>From the above definition I understand there are three "Identities" for
any

Source statement.

1.       SEU statement number ( I have no confusion on this)

2.        Source IDs  ( I am confused about this --- where is this
found? )

3.        Statement_Number ( I am confused about this too.-where do we
find this?)

 

            So in a nutshell my doubt is about Source IDs & Statement
Number

            Where are they found and what is their relevance?....If they
are both found in

            Compiler listing (spool generated) , what is the
significance of having both of 

            Them ?. 

 

            Thanks in Anticipation,

Regards,

S.Chand
