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

Registers the function name, making it available to REXX procedures. A return value 0 signifies successful registration. A return value 1 signifies that the function is already registered.

rxfuncadd('SysCls','rexxutil', 'SysCls') -> 0 /* if not already registered */
-> 1 /* if already registered */


I know that I can use a dll with CreateObject.
But I don't know how I can use the functions etc...
