Indirect call of a program programmed in ISO language (ISOCALL)
A program programmed in an ISO language can be called using the indirect program call
ISOCALL. The ISO mode set in the machine data is then activated. The original execution
mode becomes effective again at the end of the program. If no ISO mode is set in the machine
data, the subprogram is called in Siemens mode.
