Precautions
(1) Program error (P232) results when the designated program number (P) is not located.
(2) Single block stop does not occur with the M98P__; M99; block. If any address except O, N, P,
L or H is used, single block stop can be executed. (With X100. M98 P100;, operation branches
to O100 after X100. Is executed.)
(3) When M99 is commanded by the main program, operation returns to the head. (This is same
for MDI.)
(4) Operation can branch from BTR operation to a subprogram by M98P__ but the sequence
number of the return destination cannot be designated with M99P__;, (P__ is ignored.)
(5) Bear in mind that the search operation will take time when the sequence number is designated
by M99P__; .
