Last week, with a group of friends examined different development possibilities for Amiga. We were searching for small footprint (low memory usage) soultions. Then we stumbled upon -now deprecated version of- purebasic.
It worked and performed fine, yet developing under winuae with 25 year old environment was pain in the ass.
Then I decided to create a PureBasic Amiga syntax highligter for notepad++. It includes all documented commands for Amiga version of Purebasic 4.00.
To use this file, goto notepad++, Languages > Define Your Language > Import… and select provided xml file. RESTART notepad++ before use.
