The CL data type "*DEC" is the RPG data type called "packed".  Try
defining "TestDate8" as "8P 0" instead of the zoned decimal "8S 0" 
format.   

Not sure about the "Const", or what it would do to something passed from
a CL program.   A CL program can't define a constant parameter, and have
no idea what happens when you use a procedure interface with CONST and
call it without the CONST.   If you continue to have problems, I'd suggest
removing the CONST as well.

Oh, and save yourself the trouble of trying VALUE, you can't pass by
value from CL, either.

Yes, I'd imagine you'd need to move the input parm to convert it from
packed to a date field.  Something like this (untested) should work
nicely:

CL0N01Factor1+++++++Opcode&ExtFactor2+++++++Result++++++++Len++D+HiLoEq

P IsRchStrD8      B                   Export
D IsRchStrD8      PI             1A
D   TestDate8                    8P 0

D MyDateVar       S               D

C     *ISO          test(D)                 TestDate8              99
C                   if        *in99 = *on
c                   return    'E'     (for error)
c                   endif
C*
c     *ISO          move      TestDate8     MyDateVar
C*
C                   return    IsRchStrDt(MyDateVar)
P                 E



And then something like this:

PGM

        DCL VAR(&MYDATE) TYPE(*DEC) LEN(8 0)
        DCL VAR(&RESULT) TYPE(*CHAR) LEN(1)

        callprc IsRchStrD8 parm(&myDate) rtnval(&result)

ENDPGM
