Features New to QuickBASIC 4.5
 
You can now access on-line help for QuickBASIC's keywords, commands,
and menus, as well as general topics and your own variables. Examples
shown on help screens can be copied and pasted directly into your
own program, reducing development time.
 
Mouse users can now set the function of the right mouse button with the
Right Mouse command from the Options menu. Use the function that best
suits your needs.
 
For faster debugging, QuickBASIC now offers an Instant Watch command
for immediately identifying the value of a variable or the condition
(true or false) of an expression.
 
Version 4.5 also lets you set default search paths to specific types
of files. This lets you organize your files by type and keep them
in separate directories. QuickBASIC will search the correct directory
after you set the new default search path. You can set default paths
for executable, include, library, and help files.
