Update of bug #54892 (project octave):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed                 


Follow-up Comment #1:

This is expected.  See the documentation for sscanf.  The third argument is
the number of times the pattern should be read.  It defaults to Inf, in other
words, as many as possible.  You can check this by using the second output
argument which returns how many pattern was applied.

octave:11> [h,n] =sscanf(g,"%1c") 
h = Hello World
n =  11

Here's an example of reading a single character with sscanf.

octave:13> [h, n] = sscanf (g, "%1c", 1)
h = H
n =  1
