@REM - ReadAFile.BAT (17 Jul 2024 // 17 Jul 2024): Innovative Way to Read a File and Save Each Line as a Variable
@ECHO OFF

::: This script will read an input file with up to 1000 lines (#MAXLINES=999) 
 ::: and save each line as a variable (#LINE000000 to #LINE000999) as necessary.
 ::: How high you can go will depend on system memory, and possibly some other 
 ::: heap or stack resource.  The largest file I tested was one with 823 lines.
 :::
 ::: You would call this from the command-line as:
 :::   ReadAFile.BAT "x:\Some\Folder\InputFile.TXT
