SA0078: Missing CASE branches

Detects ‎CASE‎ statements without ‎CASE‎ branches and only one ‎ELSE‎ statement

Justification: A ‎CASE‎ statement without cases wastes execution time and it is difficult to read.

Importance: Medium

Example

PROGRAM PLC_PRG
VAR
	iVar : INT;
	xTemp : BOOL;
END_VAR

iVar := iVar + INT#1;
//in the following the case descriptions are missing:
CASE iVar OF           
	ELSE
		xTemp := NOT xTemp;
END_CASE
