I don't recall, it's been too long. Was the version of BASIC in the IBM
PCjr called GWBASIC? I did notice strong similarities between the code my
friend shared with me and the Coco's ECB. He used a lot of LINE commands,
which were very similar in syntax to the Coco's LINE command. Did GWBASIC
have the 'DRAW' command. My friend certainly didn't use it in his code.
