Subroutine Area SUBROUTINE
AREA
Establishes the boundary between main program and
subroutine area. Subroutine area is not scanned unless
directed to do so by a JSR instruction.
-(LBL)- Label XX
-(LBL)-
This condition instruction is the target destination for JUMP
and JSR instructions.
XX-two digit octal identification number, 00-07
-(JMP)- Jump XX
-(JMP)-
When rung is true, processor jumps forward to the referenced
label in main program.
XX-two digit octal identification number. Same as LBL with
which it is used.
-(JSR)- Jump To Subroutine XX
-(JSR)-
When the rung is true, processor jumps to referenced label in
subroutine area.
XX-two digit octal identification number. Same as LBL with
witch it is used.
-(RET)- Return -(RET)- No identification number. Can be used unconditionally .
Returns the processor to the instruction immediately following
the JSR in the main program that initiated the jump
