Pointer Arithmetics still cannot generate correctly #416
Description
Describe the bug
Pointers can now be assigned to and from numbers, but additions on these pointers still fail
To Reproduce
The following function from oscat still fails with the issue :
Error: Invalid types, cannot generate binary expression for "__BIN_TO_BYTE_pt" and "DINT"
FUNCTION BIN_TO_BYTE : BYTE VAR_INPUT BIN : STRING[12]; END_VAR VAR pt : REF_TO BYTE; i: INT; X: BYTE; stop: INT; END_VAR (* version 1.226. jul 2009 programmer hugo tested by oscat BINARY_TO_byte converts a binary string into a byte. *) (* @END_DECLARATION := '0' *) pt := &(bin); stop := LEN(bin); FOR I := 1 TO stop DO x := pt^; (* calculate the value of the digit *) IF X = 48 THEN BIN_TO_BYTE := SHL(BIN_TO_BYTE,1); ELSIF X = 49 THEN BIN_TO_BYTE := SHL(BIN_TO_BYTE,1) OR 1; END_IF; pt := pt + 1; END_FOR;
