Ken, this is not true.  Calling CL from RPG with numeric parameters works
fine as long as the RPG parameter is packed, with the same length and
number of decimals as the CL expects.  (This is true for a program in
any language calling CL, including a CL program.)

When you use character fields to pass numeric parms to CL, how do you
handle negative values?

(The 15,5 thing is about calling programs from the command line, not
program-to-program.)
