Autoscript has been "retired".
The reason being is that there is no longer any need for autoscript in newer Microsoft operating systems.
The original requirement for Autoscript came from the change in behavior from DOS to the DOS in Windows 3.1/95, whereby lines of a batch file would be executed without waiting for the return on the previous command.
This caused a problem for Monarch (those many years ago..) for users that wanted to perform a routine whereby monarch would export 1 or more files, then read those back in in the next line, so it was paramount that the next line of the batch file did not execute until the last command had completed.
Now, the behavior is back to the DOS days in Windows, so that you can just write a straight .bat or .cmd file (NT-style systems) and execute it with Monarch, safe in the knowledge that the commands will complete in order and after the previous command has completed.
