Re: MATAGPAT strange behavior?

AUTO or STAT, same bug.

This seems a bug to me: the MATAGPAT option X"02" on V5R1 doesn't honor the
template value I specify in position 1-4 (the "number of bytes provided for
materialization").  Instead MATAGPAT returns the entire list of program
activations, clobbering my storage after my template declaration.

dcl dd     Template    auto char(8192);
dcl dd     *           def(Template) pos(1) bin(4) init(64);
dcl dd     Test        def(Template) pos(65) char(16) init("THIS IS A
TEST");
dcl spcptr ?Template   auto init(Template);

matagpat ?Template, GroupMark, X"02";

/* this instruction returns more than 64 bytes                   */
/* variable "Test" is now clobbered with activation list entries */
