The indicator function displays application specific alarms or the "working" indicator, or both, on the FMLI banner line. The argument string is a string to be displayed on the banner line, and should always be the last argument given. Note that string is not automatically cleared from the banner line.
The -b option rings the terminal bell n times, where n is an integer from 1 to 10. The default value is 1. If the terminal has no bell, the screen is flashed instead, if possible.
The -c option defines the column of the banner line at which to start the indicator string. The argument column must be an integer from 0 to DISPLAYW-1. If the -c option is not used, column defaults to 0 .
The -l option defines the maximum length of the string displayed. If string is longer than length characters, it will be truncated. The argument length must be an integer from 1 to DISPLAYW. If the -l option is not used, length defaults to DISPLAYW. Note that if string doesn't fit it will be truncated.
The -o option causes indicator to duplicate its output to stdout .
The -w option turns on the "working" indicator.
When the value entered in a form field is invalid, the following use of indicator will ring the bell three times and display the word WRONG starting at column 1 of the banner line.
invalidmsg=`indicator -b 3 -c 1 "WRONG"`
To clear the indicator after telling the user the entry is wrong:
invalidmsg=`indicator -b 9 -c 1 "WRONG"; sleep 3; indicator -c 1 " "`
In this example the value of invalidmsg (in this case the default value Input is not valid), still appears on the FMLI message line.
