(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Error
code
After the CALL(P), FCALL (P), ECALL (P), EFCALL (P) or XCALL
4211 instruction was executed, an END, FEND, GOEND, or STOP
instruction was excected prior to the RET instruction.
The RET instruction was executed prior to the CALL (P), FCALL (P),

Function
(1) When FCALL(P) is executed, the non-execution processing of the subroutine program of the pointer designated by Pn is
performed.
The FCALL (P) instruction can execute subroutine programs designated by a pointer
within the same program file, and subroutine programs designated by common pointers.
(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.
