K2 support

Pressing the K2 key has a limited scope. It allows the program to be interrupted in statement mode (//). After an interruption using the K2 key, the user is in command mode (/).

If K2 is pressed during the ADD-FILE, EXTRACT-FILE or SHOW-FILE-ATTRIBUTES statements, BS2ZIP interrupts processing or output with the query message SZP0208. Users then have the following options:

• They can simply continue current processing.

• They can abort current processing. When they do this, they return to statement mode (//). The statement may need to be reissued for files which had not been processed by the time the interruption occurred.
