SuperBASIC Compilers
A compiler takes the contents of a BASIC program and undertakes various processes in order to convert it to a much faster program which can run in Machine Code.
Not all compilers operate in the same way, as some generate intermediate code which is then interpreted at runtime, whereas others generate pure machine code.
There are three different SuperBASIC Compilers which were produced for the QL:
QLiberator
Supercharge
Lightning Compiler - never released
Turbo
