Celtic is a toolkit for BASIC programs by Iambian, one of the oldest member of the forum if we count the original yAronet Omnimaga board, designed to edit or pull together other BASIC programs into a custom-made file that is ready for execution. It features the ability to read lines from either RAM or Flash (archive), the ability to insert, delete, or overwrite lines in a specified program, to create a specified program and to find out how many lines there are in a BASIC program, and to output special characters into a string that is not normally storable into a string via any other method (doublequote and sto).
It is now avaliable for download in our calculator RPG and programming tools download section under TI programming tools.
