ACE is a PD Amiga BASIC compiler which, in conjunction with A68K and Blink produces standalone executables. No special run-time shared libraries are required. The language is both a subset and superset of AmigaBASIC with many features not found in the latter such as: turtle graphics, recursion, SUBs with return values, structures, arguments, include files, a better WAVE command which allows for large waveforms, external references, named constants and several extra functions.
