EFCALL(P)
Function
(1) When the EFCALL(P) instruction is executed, the non-execution processing of the
subroutine program of the pointer designated by Pn is performed.
(a) Non-execution processing is identical to the processing that is conducted when the
condition contacts for the individual coil instructions are in the OFF state.
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)
