Post subject:  Tokenizing an ASCII into BASIC
I do most of my coding on Linux; it's where I have my tools. But going from an ASCII file into a BASIC program is a bit of a pain; currently I store it as ASCII on an SSD, load the SSD into BeebEm, *EXEC it, save the results.

Does anyone know of a tokenizer that'll make my life easier?

There's some C code, courtesy of Thomas Harte, on the Sample Code page of this very website, which does exactly this - converts an ASCII BASIC program into a tokenised form, ready for putting on a disc image or feeding to a Beeb in some other manner.

I incorporated the code into BeebAsm, in case you use that, and is available in the form of the PUTBASIC command.

Huh? Oh! I hadn't even noticed those links along the top! I'm so used to forums saying exactly the same thing at the top...

Thanks! That'll help a lot.

Heheh, that indicated an "error" with TOOLKIT PLUS :-)

I had a line "ON ERROR PRINT...." which I then edited with Toolkit Plus to REM out. So the resulting code is:
Code:
 2250REM ON ERROR PRINT'"Error detected":GOTO ERL+10
 2260CALL read
 2270REM ON ERROR OFF
 2280=?result


Thomas's program:
Code:
00001040  08 CA 31 F4 20 4F 4E 20   ..1. ON
00001048  45 52 52 4F 52 20 50 52   ERROR PR

00001098  0D FF                     ..


Toolkit Plus:

00001048  85 20 F1 27 22 45 72 72   . .'"Err

00001080  65 73 75 6C 74 0D FF      esult..

We can see the words after the REM have remained tokenized and weren't converted back into ASCII.

Very funny!
