Specifying command options using a file

Top  Previous  Next

There are scenarios where it would be advantageous to place the TwainSave commands in a file, and have TwainSave read the file to obtain the commands, instead of listing the entire TwainSave command list on the command-line.


The following two scenarios can occur:


The number of characters in the command-line exceeds the limit imposed by the operating system.
The command-line is constantly changing, and changing the TwainSave commands on the command-line becomes prohibitive due to the constant number of changes.


To address these issues, TwainSave allows the commands to be placed in a file.  The -@ command option allows this.
