Some string and array functions to make getting data out of a text files easy, without using stringlists or functions that would haul in a lot of classes. Sometimes you find a StringList <b>overkill</b> - these are some simple but powerful string & array operations.

 -GetFileSize <i>text or binary file</i>
 -StrLoadFile, StrSaveFile (FileToString, StringToFile)
 -GetLn1, GetLnN, GetLineCount 
 -ArrayLoadFile, ArrayLoadLines, ArrayLoadRng   
 -StrLoadLines, StrLoadRng 
 -OpenFile and FileExists without using sysutils
 -GetLineCount of file
