Displaying Text on the
OCS Command Input
Line
You can use the CMDLINE verb from an NCL process to display text on the OCS
command input line. You can write any command text on the command input line.
You can position the cursor to any location within the command text.
The text starts from the second position after the CMDLINE verb (the first position
after the CMDLINE verb must be a blank). Leading blanks are preserved. Uppercase
and lowercase letters are preserved in the text. If the text exceeds the length of the
OCS command input line, it is truncated. Any text currently in the OCS command
input line is erased when the CMDLINE verb is executed.
You can use an underscore (_) to position the cursor within the text. The cursor is
positioned at the precise location at which the underscore appears. NCL interprets
only the first occurrence of an underscore as a positional indicator. If you do not
supply an underscore, the cursor is positioned at the end of the text.
You can use the CMDLINE verb to provide default entry values associated with the
PAUSE verb. You can place the default values directly into the command input line
for immediate entry or modification before entry.
