			To create a library out of the example above, simply change the DEF line to this:

			01100 def LIbrary fnPrintReport(NextFileKey$;___,PN,Index,ThisVersion)

			To access it from another program, use a line like this (PrReport is the name of the program the library function is found):

			05000 LIBRARY "PrReport": fnPrintReport
			05010 LET fnPrintReport(CurFile$)

			The LET statement will run the function, passing in the variable CurFile$ to be used in the function as NextFileKey$.

	User defined functions can do anything you want them to do. They must start with the letters FN but contain custom code. Variables can be passed in and out of functions. If something calls a function that starts with FN, then you can find the definition of that function by listing for it.		User defined functions can do anything you want them to do.

			01100 def fnPrintReport(NextFileKey$;___,PN,Index,ThisVersion)
			.... function code
			01500 end def

			In this example, the user defined function is called fnPrintReport, and the above variables are passed into it. NextFileKey$ is required, but variables following the semi-colon are optional and will be set to null if not passed in.

	To remove some of the repetitiveness of coding. BR allows you to place code in functions in certain programs, which become libraries, to be used from other programs. Fileio is an example of this. It provides functions for opening, reading, writing and rewriting data by calling library functions and passing variables through them. Complete documentation is available on the wiki and from ~~Sageax~~. Or you can create your own.		To remove some of the repetitiveness of coding.

User defined functions can do anything you want them to do. They must start with the letters FN but contain custom code. Variables can be passed in and out of functions. If something calls a function that starts with FN, then you can find the definition of that function by listing for it.
