What were the MS-DOS programs that the moricons.dll icons were intended for?

Word Perfect!!! I'm almost positive that was the editor they taught me in the early 1990s in grammar school! (We called it grammar school back then, for it was the 1800s.) And yet I had never seen or used it since. This brings back so many memories. I was sitting next to a girl named Dana, the only Dana I ever met.

It was huge back then, but it tanked in the transition to Windows. I kept using the DOS version for years after that because I had muscle memory for WordPerfect’s shortcuts and liked the reveal codes feature.

Also I’ve met two Danas that I can remember. Both were lovely people.

I recall hearing that WordPerfect usage survived longer in the legal field.

I also remember in the late 90s, before StarOffice/OpenOffice/LibreOffice took off, WordPerfect had a resurgence on Linux, because there was a need for a word processor. I seem to recall a distro shipping with it prominently. Was it Corel Linux?
