This function calls one of several low-level subroutines built into FB. The fnIndicator parameter indicates which routine to call; use one of the constants shown in the table below.

NEED IMAGE!!!!!

Example: One of the most useful USR functions is USR _fileAddr. You can use the LOCAL FN shown here to display information about an open file. LOCAL FN DisplayFileInfo(fileID) pbPtr& = USR _fileAddr(fileID) LONG IF pbPtr& <> _nil

Don't know what the print thing is
