Big and not clever.
Word for Windows (version 2 or whatever) did the job. Since then the program has multiplied in size. Doubtless, lazy coding and adding stupid features -- I get angry when Word starts capitalising words or creating bullet points, unasked.
When I first started computing, Superwriter supplied free with the Apricot would run from a floppy disk with room left for documents. In fact, I ran it from a virtual disk, so it started instantly. Word now comes on a DVD ??
Oh and Word versions recently started saving .doc files as .docx just to madden us further. Hopefully, the subscription sales model will kill it off.
