Appendix B. Correlating Scanner and Reporter output to
source
This appendix describes how to match the EXEC CICS command in the Reporter
report and/or the Scanner detail report with the actual program source code. It also
gives some examples of the procedures described.
Reporter output
The reported offset of a command is the offset from the start of the load module of
the BALR to the CICS stub. To get the offset from the start of the program, subtract
the length of the CICS stub from the offset reported. (You may also need to subtract
the lengths of any additional preceding CSECTs.) You can then use the compiler
listing to find the command.
Scanner output
The reported offset of a command is the offset from the start of the load module of
the CICS command argument zero.
6
This is a constant and is therefore located in
the literal pool for the program. As with the Reporter, subtract the length of the
CICS stub and preceding CSECTS to get the offset from the start of the program.
You should then be able to locate the argument zero in the compiler listing. Next,
match the argument zero to the command, which involves finding the instruction
that referenced the argument zero, using the compiler listing.
Examples
This section gives some examples of the procedures for the Scanner.
Example 1–Assembler-language
Before the BALR to the CICS stub, the CICS translator generates an LA instruction
with the argument zero as source. For example:
LA 14,=X'02028000080700000000000000000000000000000000'
To locate the EXEC CICS command, you can match the argument zero in the literal
pool with the same argument zero in the LA instruction.
6. For an explanation of argument zero, see “Notes on terminology” on page x.
