User`s guide
arg_list is the list of arguments being passed to the subroutine. These arguments
can be passed either by value or by reference and must agree with the
arguments expected by the program being called. Subroutines and
argument lists are described in "Subroutines."
The code:
48 .
49 CALL check_data(locx, locy, length)
50 .
suspends execution of the calling program, passes the arguments locx, locy, and length to
program check_data, executes check_data, and (after check_data has completed execution)
resumes execution of the calling program at step 50.
CALLS
The CALLS instruction is identical to the CALL instruction except for the specification of
program. For a CALLS instruction, program is a string value, variable, or expression. This
allows you to call different subroutines under different conditions using the same line of
code. (These different subroutines must have the same arg_list.)
The code:
47 .
48 $program_name = $program_list[program_select]
49 CALLS $program_name(length, width)
50 .
suspends execution of the calling program, passes the parameters length and width to the
program specified by array index program_select from the array $program_list, executes the
specified program, and resume execution of the calling program at step 50.
