API Functions


The following built-in REXX functions can be used in a REXX program to 
register, drop, or query external function packages and to create and 
manipulate external data queues. 
RXFUNCADD 

 >>-RXFUNCADD(name,module,procedure)--------><

RXFUNCADD registers the function name, making it available to REXX 
procedures. A zero return value signifies successful registration. 
RXFUNCDROP 

 >>-RXFUNCDROP(name)------------------------><

RXFUNCDROP removes (deregisters) the function name from the list of 
available functions. A zero return value signifies successful removal. 
RXFUNCQUERY 

 >>-RXFUNCQUERY(name)-----------------------><

RXFUNCQUERY queries the list of available functions for a registration of 
the name function. The function returns a value of 0 if the function is 
registered, and a value of 1 if it is not.

              +--"Set"------newqueuename-+
