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

If the program is to be initiated by a WFL RUN statement entered at an ODT, 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.
