CALL (FNC 01)
Points to note:
a) Many CALL statements can reference a single subroutine.
b) Each subroutine must have a unique pointer number. Subroutine pointers can be selected
c) Subroutines are not normally processed as they occur after an FEND instruction. When
d) Subroutines can be nested for 5 levels including

the initial CALL instruction. As an example the
program shown opposite shows a 2 level nest.
When X1 is activated the program calls subroutine
P11. Within this subroutine is a CALL to a second
subroutine P12. When both subroutines P11 and
P12 are active simultaneously, they are said to be
nested. Once subroutine P12 reaches its SRET
instruction it returns the program control to the
program step immediately following its original
CALL (see
and once its SRET instruction is processed the
program returns once again to the step following

Operation:
When the CALL instruction is active it forces the
program to run the subroutine associated with the
called pointer (area identified as subroutine P10). A
CALL instruction must be used in conjunction with
FEND (FNC 06) and SRET (FNC 02) instructions. The
program jumps to the subroutine pointer (located after
an FEND instruction) and processes the contents until
an SRET instruction is encountered. This forces the
