Adrian,

MODASA is used to allocate automatic storage much like using alloca() in C.
The received parm would already have it's storage allocated prior to calling
your program.  If you need to make a copy of the parm, then MODASA could be
used.

Copying variable length data can done using the qualifiers of
(startpos:length). For example:
CPYBLA   SOMEVAR(1:PARM2),  PARM1(1:PARM2);

A code example describing what you mean by "handle" might help.

Subject: [MI400] Variable length parameter


Hi guys,
here's my question : how do I handle a variable length parameter in a MI
program provided I receive its length as parameter as well.
I tried using the MODASA instruction but I don't seem to find the way of
geting it work.
The program should receive in the 1st parm a variable length buffer and the
second would be the length of the first.

Thanks,
Adrian
