Properties of the subprograms

General rules
● The subprogram called when making the replacement can contain the command PROC and
the attribute SBLOF and DISPLOF.
● The replacement is also made in the ISO language mode. However, the replacement
subprograms are exclusively processed in the standard language mode (Siemens). There
is an implicit switchover into the standard language mode. The original language mode is
reselected with the return jump from the replacement subprogram.
● System variables are exclusively used to transfer information to the replacement
subprogram. Transfer parameters are not possible.
● The behavior for a single block and attribute SBLOF depends on the setting in:
MD10702 IGNORE_SINGLEBLOCK_MASK, bit 14 (prevent single-block stop)
