I realize this general issue (inputting strings of variable length in C) has been addressed in myriad locations before, but I'm interested in knowing why my specific approach is not working. (BTW I'm intentionally keeping the size increments small so that I can more easily follow what's going on. After it works on a small scale, I can increase the size to something more reasonable. The main motivation for this approach is that I want to increase the size by a fixed increment, not by doubling the allocated memory each time.)
Here is the code:
The code works fine for short strings, but stops working (program seems to get stuck) if string is longer:
I'm a newbie in C and would like to learn something by debugging this.

indicator
indicator(1F) FMLI Commands indicator(1F)NAME
indicator - display application specific alarms and/or the "working" indicator
SYNOPSIS
indicator [ -b [n]] [-c column] [-l length] [-o] [-w] [string...]
DESCRIPTION
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.
OPTIONS -bn 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.
-c column 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 .
-l length 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 DIS-
PLAYW. Note that if string doesn't fit it will be truncated.
-o The -o option causes indicator to duplicate its output to stdout .
-w The -w option turns on the "working" indicator.
EXAMPLES
Example 1: A sample output of the indicator command.
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.
