" Applied IBasic support to the already excellent support for standard

" basic syntax (like QB).
|

" First version based on Micro$soft QBASIC circa 1989, as documented in

|
|
" 'Learn BASIC Now' by Halvorson&Rygmyr. Microsoft Press 1989.

|

" This syntax file not a complete implementation yet.
|

|
|
" Send suggestions to the maintainer.
|
||
|
|
"
|
||
|
|
" This version is based upon the commands found in IBasic (www.pyxia.com).
