# Category:UBasic/4tH

**uBasic** (not to be confused with UBASIC) is an integer Basic interpreter in the tradition of Tiny BASIC, with which it is largely compatible. This version is entirely written in 4tH, some bugs have been removed and several additional features have been added, like user stack support and structured programming:

`PUSH, POP()`and`TOS()`can be used to emulate`DATA`statements, pass parameters to subroutines or make recursive subroutines;`DO, LOOP, UNTIL, WHILE, CONTINUE`and`BREAK`supported;- Multi line
`IF..THEN..ELSE..ENDIF`supported; - Parameter passing supported by
`GOSUB`,`RETURN`,`PROC`and`FUNC()`extensions; - Local variables supported, both initialized and uninitialized;
- Alphanumeric labels supported;
- String support with automatic
*and*manual "garbage collection"; - Exception handling, using
`TRY()`and`RAISE`; - Text file support with read, write and append modes;
- Input parsing, using
`TOK()`and`SKIP`; - "Structured Basic" commenting style.
