Transfers control to the statement containing the next M (mark) command.
The program is scanned forward from the current line, until the next M command is found. Program execution then jumps to that line.
If an M command cannot be found, the jCL program will terminate with an error message:
Can't find mark at line n in programname
005 GO F
006 10 MV %1 "ABC"
007 MV %6 "DEF"
008 MV %10 "HIJ"
The GO F command on line 5 causes the program to be scanned from line 6, looking for the next M command. In this case, control will be transferred to line 9.
