Detects the use of expressions in the declaration of array indexes
Justification: Not all systems permit expressions as array limits.
Importance: Low
Example
PROGRAM PLC_PRG VAR CONSTANT c_iValue : INT := INT#15; END_VAR VAR arr: ARRAY[0..c_iValue + 1] OF INT; END_VAR --> SA0122: Only constants allowed for array definition 'arr'
