So did BASIC and some forms of batch file.

I used 4DOS batch language to write the first program I ever made for
others to use. I was at a center for the blind. The program took a CD-ROM
full of ebooks that were zip files each containing a single .txt file.
Using a catalog, it organized that collection into directories named for
authors, with the extracted .txt files renamed to contain the title. Yeah,
the input was 8.3-style DOS filenames, and the output used Win 9x long
filenames.

I was doing most of this in my spare time, writing code on a PDA-like device
with a Z80 microprocessor, no 4DOS interpreter in sight. Essentially I was
coding by reading the 4DOS documentation.
When I did have access to a PC with 4DOS, I'd test pieces of the thing.

I had it make little beeps to indicate progress. Wanna guess how exciting
it was to watch that thing run and hear those silly beeps?

I was no programmer at the time; just a person with a brain and great reading
comprehension.
