SA0005: Invalid addresses and data types

Detects invalid addresses and data type specifications. Valid size prefixes in addresses: X for BOOL B for 1-byte data types, W for 2-byte data types, and D for 4-byte data types.

Justification: Variables located on direct addresses should preferably be associated with an address that corresponds to their data type width. It can be confusing for the reader of the code, for example, if a DWORD is assigned to a BYTE address.

Importance: Low

Example 58. Example
PROGRAM Check_Address_Type_PRG
VAR
    iVar AT %QB0 : INT ;   // OK e. g.: %QW0
    xTest AT %QW1 : BOOL ; // OK e. g.: %QX1.0
END_VAR
iVar := iVar + INT#1;
xTest := NOT xTest;
