When you encounter an error in
a program, there are several ways
to locate the error.
- The TRACE instruction shows how the language processor evaluates
each operation. For information about using the TRACE instruction
to evaluate expressions, see section Tracing Expressions with the TRACE Instruction. For information
about using the TRACE instruction to evaluate host commands, see the next
section, Tracing Commands with the TRACE Instruction.
- REXX/CICS sets the special variables RC and SIGL as follows:
- RC
- Indicates the return code from a command.
- SIGL
- Indicates the line number from which there was a transfer of
control because of a function call, a SIGNAL instruction, or a CALL
instruction.
