SA0060: Zero used as invalid operand

Detects operations where an operand with the value "0" causes an invalid or a nonsense operation

Justification: This kind of expression could be an indication of a programming error. In any case, it unnecessarily wastes runtime.

Importance: Medium

Example

PROGRAM PLC_PRG
VAR
	byTemp1 : BYTE;
	wTemp2 : WORD;
	dwTemp3 : DWORD;
END_VAR

byTemp1 := byTemp1 + 0;
wTemp2 := wTemp2 - WORD#0;
dwTemp3 := dwTemp3 * DWORD#0;
