- IF and WHILE condition logical operators usage:
  - Currently there is no ultimate determination of which type to use when comparing two values (.byte, .word), so I recommend using variables of type INT or CARD when comparing them with logical operators
  - AND and OR are not allowed on the same line
  - When logical operators are used, ==, <= and >= are not allowed

- PrintF command
  - BYTE variables do not comply
  - Comments are not applicable
  - Comma characters are not allowed

- Only one command allowed on any line

- Arrays and pointers not fully supported

- Comments raise errors in some occasions:
  - CARD POINTER ptr
  - ptr^=251
- Some commands are not allowed in commands for printing text on the screen. For Example using PROC, FUNC, or ELSE statements in PrintB and PrintBE commands.
