PROMAL features simple syntax, no line numbers, long variable names, functions and procedures with argument passing, real number type, arrays, strings, pointer, and a built-in I/O library.

Like ABC and Python, indentation is part of the language syntax.

The language uses a single-pass compiler to generate byte code that is interpreted when the program is run.

The software package for C64 includes a full-screen editor and command shell.

It concluded "As an introduction to structured programming languages and as an alternative to BASIC, PROMAL is well worth the time needed to learn it and the $49.95 to purchase it".
