If you are designing a program to be initiated by the PRIMITIVE RUN command, be aware that the program cannot receive any parameters.

If the program is to be initiated by a WFL RUN statement entered from Operations Center, the program can receive the four parameter types passed by WFL: Boolean, integer, real, and string. The string parameter should be declared in the program as a real array (or compatible parameter type) with an unspecified lower bound. For information about real array parameters and compatible parameter types, refer to Using Parameters.
