A library, typically, is a file that contains a set of functions and subroutines that pertain to a given task. They are all grouped in a bas module and can be compiled with the compiler as a lib or a quick library (to be loaded in the IDE of the Basic implementation that you use).
In other words, libraries are a good thing for organizing your code into functional groups for one thing.

NO!
A library generally has DEFINITIONS of functions + subs. There's a difference.

No, this is defining a sub or function:
Code: Select all
SUB MySub (A, B, C)
B = A + B
C = B + C
A = A + B * C
'other code
END SUB
That's the definition of a sub or a function....
This is how you call a sub or function:
In Mystiks terms he was refering to the declarations which are the ACCUAL subs or functions in the program, the definitions just define them, the computer doesn't go to the definitions when it is called:
Those ARE the terms...I definatly remeber that....MystikShadows WAS right but I was just correcting him on his terms....

Incorrect. A library is a binary file which is a collection of procedures that is linked into the program with the linker. The definitions are kept elsewhere, usually in a header file. I believe you're getting things confused with how FB works...and even there, the concept of a library is still the same...it's just that some people believe .a files to be libraries when they're not always libraries but sometimes simply definitions.
