1. Edit the BASIC text file using your favorite editor
2. Import the file
2.a. Using DOSLink if using Emu71
3. TRANSFORM the text file INTO BASIC

Just curious, I tried this some weeks ago without success. The DOSLINK copy wasn't coming to an end.

Hi Christoph,

From the 2014 Allschwil meeting, http://www.jeffcalc.hp41.eu/hpil/files/doslink.pdf

Slide 2 suggests this use: Example: importing a program from a PC text file. Seems like that's exactly what I stated. You do need to execute CLEAR :LOOP or CLEAR :DOSLINK to close the files. The hassle with this method is prepending the LIF header to the text file. For that reason I prefer to use pyILPER as a front-end for the Python version of Tony Duell's LIFUTILS.

PC ASCII files and HP71 text files are exactly the same. It's the 75 that has a non-standard text file format. PC ASCII text files are supported on the 75 as LIF1 "Interchange" files.
