--- 1.3.2 ---

|

* Print file listing or full disk listing (including subdirectories or multiple
|
||||
volumes).
|
||||
|
||||
--- FUTURE 1.3.x ---
|
||||
o Compile of BASIC programs
|
||||
@ -12,13 +13,13 @@ o Add Apple Pascal writing capability.
|
||||
o Create subdirectories as appropriate (ProDOS).
|
||||
o Need to update preferences with import location, disk creation location.
|
||||
o Enhance the BASIC compiler with a few more commands...
|
||||
o Print file listing or full disk listing (including subdirectories or multiple
|
||||
volumes).
|
||||
o Improve file preview for Integer BASIC files.
|
||||
o Improve file preview for AppleWorks Word Processor files (make implementation
|
||||
generic to a Word Processor).
|
||||
o Add formatted assembly FileFilter. Needs to understand multiple assembly programs.
|
||||
Need to recognize various formats - T.*, *.S, etc. (Merlin, Orca, APW, etc).
|
||||
o SWT image handlers do no appear to work correctly. BMP works - but color seems
|
||||
off. GIF/PNG/JPEG give errors or a black image.
|
||||
|
||||
--- FUTURE 1.4.x (or later) ---
|
||||
o Add drag-and-drop capability.
