Synopsis

Documentation

place the file handling to a specific SeekTarget provided a function that extracts a value/entry at a specific position

Constructors

StLargerThan !b	put the handle to the first entry that is larger than the provided value. Useful for files with entries in ASCending order
StSmallerThan !b	put the handle to the first entry that is smaller than the provided value. Useful for files with entries in DESCending order
