CLLE calling RPGLE sends bad parms???

CL is passing the parameter by reference (i.e. a pointer is passed to the
RPG procedure).  By coding the parameter as VALUE you specified that the
data be passed.  When using RPG to call the routine the compiler honors the
prototype and passes the parm by value, CL can't see the proto and so does
"what comes naturally".  Just drop the VALUE keyword and you'll be fine.  If
you need the flexibility afforded by VALUE when calling from RPG (i.e. being
able to use an expression, literal or constant as the parm) then substitute
CONST for VALUE.

Read the good 'ole RPG Redbook ("Who Knew ... etc.") for more details on
parameter passing conventions and associated prototype keywords.
