Block
Data Transfer
The first key definition sent is the one on the line on which the cursor is located.
In Block Page mode, all of the function key definitions, from the cursor row to the end of the
menu, are transmitted. Then, the cursor is positioned on the blank line following the last
function key definition.
In Character or Block Line mode, only one key definition is transmitted, but the cursor is
always moved to the start of the next key definition, regardless of the state of Auto Linfeed
mode. Block terminators in the definition string are treated the same as any other character.
Non-displaying terminators are ignored.
Table 9-5 lists the end characters.
