#Compiler update: Write and writeln marks the end of the the refactoring of operations and primitives which has taken up the last few months.
I've also refactored a few other parts to better future proof them.
There a still a few rough edges to smooth off in the expression parser (implicit types) and code generator (parameter loading and validation).
But this means I can now return to interesting stuff :) as well as moving towards some kind of initial (pre-beta) release.
Output if the test program running on an Amstrad CPC emulator.
