This is my 202 bytes long interpreter, encoded with 6 bit and decoded with the one used in kintsmef. The sources of the converters are available with kintsmef. This code will be available for download on this website some time later.
Usage: "BFI.COM < TESZTFIL.BF".
Installation: put it into BFI.COM with your favourite text editor.
Needs: PC 186+, DOS or compatible.
Functions: depress [ALT] or [ALT]+[Q] to terminate the interpretation.
Enter=0x0A, 0x0A=new line. 30k data/30k code, 2k stack, fool-proof.
(Useful for debugging, testing and learning.)
Special function: "!" signals the end of a source file and the beginning of pre-stored standard input.
