Sorry, QBasic cannot utilize libraries. You'll have to use "QUICKBasic" 4.5 or better not "QBasic".
If you do get a hold of QB 4.5 you MUST begin your QB session with the library loaded at the command prompt...
examples:
c:\QB45\QB.exe /L
(Use only the L if you want to load the standard library)
c:\qb45\qb.exe /L:MyLib.qbl+SomeOther.qbl
(This one will load libraries named "mylib.qbl" and "someother.qbl" to be used in your session and eventually in your compilation)
Good Luck,
