Directives that Optimize Performance

The following Compiler directives can optimize the performance of multi-threading programs:

• PARAMCOUNTCHECK - Controls checking of number of entry point parameters
• FASTCALL - Controls the behavior of a called program

The following directive settings are made by default:

• PARAMCOUNTCHECK
• NOFASTCALL
• NOREENTRANT
• NOSERIAL

If you want your program to be optimized for speed, set the directives as follows:

• NOPARAMCOUNTCHECK
• FASTCALL
• NOREENTRANT
• NOSERIAL

However, you might have to change your program to take advantage of these Compiler directives.
