File name: Name of the program file to be called (character string)
Pn : Head pointer number of a subroutine program (Device name)
to : Number of the device to be passed as an argument to a subroutine program (bits, BIN 16 bits, BIN 32 bits)
Function
(1) Executes the subroutine program of the pointer designated by Pn in the designated program file name when the ECALL
(P) instruction is executed. The ECALL(P) instruction can be used to call a subroutine program that uses a local pointer
from a different program file.
(2) Only the file name of a program file stored in the drive 0 (program memory/internal RAM) can be designated for a file
name.
(3) It is not necessary to designate the extension (.QPG) with the file name.
(Only .QPG files will be acted on.)
