RE: F35 - Y2K

Thank you very much.  I can see now that my feeble attempt was wiping out   
the length in the first two bytes of the return variable.  :(

Here's a simple example...

Define a command parameter (*CHAR) with a length of 1 RTNVAL(*YES),   
MIN(0),
MAX(1) and VARY(*YES)

The CPP should defined with a parameter of the largest length expected   
(+2)
 - ( if you use pointers you don't have to worry about this length.) The
first two bytes of the variable will be the binary length of the actual
variable used on the command. To return a value just move that value into
the passed variable from positions 3 to the passed length.
