Make sure you are up-to-date on PTFs, as there were bugs in this
support
when V5R4 was first released.

then, simply declare a pointer variable in CL. By default, new pointer
variables are set to NULL. Use that new variable to compare with...
for
example:

DCL VAR(&LP) TYPE(*PTR)
DCL VAR(&NULLPTR) TYPE(*PTR)

IF COND(&LP *EQ &NULLPTR) THEN(DO)
