Re: ZX Basic precompiler

What your saying makes sense, but I can see the need to run a few bytes of ML code on the fly or to setup and jump into ROM to do something. Will see

Re: ZX Basic precompiler

I am thinking psuedocode something along these lines: PRINT "HELLO WORLD - THE FOLLOWING IS ML" { LD HL, 0 PUSH HL POP AF LD BC, 0 LD DE, 0 } PRINT "THAT WAS IT" and then the precompiler would turn it into 10 PRINT "HELLO WORLD - THE FOLLOWING IS ML" 20 RAND USR(ADDRESS OF LINE 30) 30 REM ......... ...

I have a game I am making in pure Basic. I am writing it using a text editor and using labels for line numbers and then using zxtext2p to make a .P file. It has 550 lines of code that replicate 220 some data statements using LET and GOTO (referenced with a computed GOSUB). If this code is in the mid...
