User define key + auto ENTER

[cclinus]

Hi,

Thanks for your suggestion.
But it is just partially successful.
The result of ENG() is came out right after pressing the key.
But, it is placed on the entry line. I still need to press Enter to complete the process.

Here is the ENG program:
EXPORT ENG(X)
BEGIN
STRING(X,4,6);
END;

THANKS!
