|Command||op.readnext Command/Output Processor: Commands
Applicable release versions: AP
|Category||Output Processor: Commands (183)|
|Description||reads data, one value at a time, from an "active list".
It has an effect only if, prior to entering OP, a "select", "sselect", "qselect" or "get-list" statement has been executed.
Each ".readnext" command in OP extracts the next value from the active list and places it in the text stream.
".readnext" does not cause a "break".
If there is no pre-selected list, or when the list is exhausted, the ".readnext" command terminates OP, and returns to the calling process.
Dear .readnext You are the only one for me. Love, Pat .chain love.letter
