Micros 3700 SIM to collect covers

[POSN]

Hello,
We're trying to collect covers via a macro and need a SIM to capture this. I tried the following from another post but didn't work. Seems like I'm missing something.
loadkybdmacro makekeys(@Gst)

Any help would be appreciated.
Thank you.

With a isl you can ask the employee to enter a cover and with a loadkbdmacro you can write it as example to the check, but the function call is missing in your part.

What is the main goal to collect the covers ?
Does it only need to show a message to the employee or do you need it in a third party system, write to the micros database in different table ?

Simple the question what should happen with the covers in your process ?

We need to report on covers. I suppose write to the DB when the check closes. Here is what it looks like without the macro.

I really do not understand because.
This data will already be written on every posting (send order, payment) in the Sybase database from 3700. And it will be shown on almost every crystal report in the reporting.
What you would like to achieve with the isl ?
