Progress with BINSIC

BINSIC – Binsic Is Not Sinclair Instruction Code – my effort to re-implement Sinclair ZX80/ZX81 BASIC as a domain specific language via Groovy (and eventually a runnable Java JAR file), is making more progress.

Right now it supports:

IF ... THEN ... ELSE
GOTO
GOSUB ... RETURN
LET
FOR ... TO ... STEP ... NEXT
DIM A(x, y, z) (and array derefencing)
CLS
PRINT

Still one or two difficult areas to get through and I have had to make one compromise – unlike on the ZX80 one cannot have a variable and an array with the same letter designation – just too difficult to implement on Java/Groovy.

But, it’s getting there…
