Hi,

I was scanning some programs and found in the program description that a particular program to be compiled with some option.

Could any one let me know what exactly is the options

NOOPT.

In what scenarios we use NODYNAM.

Thanks,

NOOPT is a compiler option which tells the compiler to not optimise the code . In the case of OPTIMISE the compiler merges and rearranges the statment in the compiled code and the result of optimised is used in the fault analysis

hi,

This is what i got,

NOOPT/OPT: This is a Compiler Option for Optimization.

Use OPTIMIZE to reduce the run time of your object program. Optimization might also reduce the amount of storage your object program uses.

Because OPTIMIZE increases compile time and can change the order of statements in your program, you should not use it when debugging.

DYNAM/NODYNAM: This is a Virtual storage usage compiler Option.

Use DYNAM to cause nonnested, separately compiled programs invoked through the CALL literal statement to be loaded (for CALL) and deleted (for CANCEL) dynamically at run time. CALL identifier statements always result in a run-time load of the target program and are not affected by this option.

Restriction: The DYNAM compiler option must not be used by programs that are translated by the CICS translator
