Hmmm... Due to your "unique" combination of KS2.x and WB3.x, you can create a text file but you'll have to do it the old-fashioned way:
1. Open a new CLI window (from Workbench, select "Execute Command" from the menu, then enter "newcli" in the resulting dialogue box)
2. Type the following into the CLI window: copy * testfile (this tells the Amiga to create a new text file called "testfile" and to accept input from the keyboard - similar to using "copy CON: " in MSDOS)
3. Enter the lines of your text file, pressing Return at the end of each one
4. Press CTRL and hash (#) to signify the end of the file
You'll then at least have a text file, into which you could place some commands...
And... I've discovered that the old line editor (called "Edit" and invoked by a command with the same name) does work, but you'll need to search for instructions on how to use this (at least "q" quits it!).
You really would be better off waiting until you get your A1200!!!
