I did some minor modifications to version 1.1.0 of the Mega Assembler.
The updates are only related to the editor.
1. You can toggle overwrite/insert mode with ESC-V
2. Overwrite mode is show in the title line (INS/OVR)
3. Tabs are now every fifth column instead of 14/32
4. Quotation mark is allowed
Disadvantage of my update (because of the "" chars): all lines of old files are quoted when loaded.
Hope you like it.
