If you are designing a program to be initiated from MARC, be aware that the program can receive only one parameter from the RUN screen or RUN command that initiates it. If the user encloses the parameter in quotation marks (“), MARC passes the parameter as type Real Array with an unspecified lower bound. If the user does not enclose the parameter in quotation marks, MARC passes the parameter as type Real. For information about the parameter types in each language that are compatible with the Real and Real Array types, refer to Using Parameters.
