I have compiled multiple QucikBASIC programs of my own creation before, but my latest program uses INTERRUPTX.
So when i try to compile it, the linker asks me to point it to the location of QB.LIB. It runs fine from inside the interpreter.
I have tried copying the file QB.LI$ from my floppy disks using the command A:\> COPY QB.LI$ C:\QB45\QB.LIB
But when i try to compile, then the linker says something along the lines of FATAL ERROR: QB.LIB NOT A VALID LIBRARY

Can anyone tell me how i can get QB.LIB? It's supposed to be a full installation of QuickBASIC.
