The maximum number of display lines that can be defined for a panel is 62. This does not include control statements. It is possible that a panel may exceed the size of the terminal or the size of the current operational window (if operating in split-screen mode). If this happens, Panel Services truncates the panel.
An invoking NCL procedure can use the &LUROWS and &LUCOLS system variables to determine the dimensions of the processing window. The &ZROWS and &ZCOLS system variables can be used to determine the dimensions of the physical terminal. The &ZCURSFLD and &ZCURSPOS system variables are used to determine the actual field which contains the cursor. Using these variables, a procedure can tailor its processing accordingly.
