title: Cannot load a file in Octave
body: <p>Apologies in advance if I get something wrong. This is my first post here (I'm sure there will be many to follow). </p>
  
  <p>I have a file I want to load into Octave but it doesn't work. It is a plain text file (.txt).
  The file is homogeneous and an excerpt of a few lines from it look like this:</p>
  
  <pre><code>0023,225.935,341.770,17.658
  0024,225.935,341.758,17.782
  LTAX17,228.152,353.935,17.665
  LTAX24,288.304,332.878,24.074
  </code></pre>
  
  <p>where the first column depicts the name of the point while the rest represent its 3D coordinates.</p>
  
  <p>Some of the options I've tried (but not limited to these) were unsuccessful.</p>
  
  <pre><code>x=load(text.txt)
  error: scalar cannot be indexed with .
  error: evaluating argument list element number 1
  
  x=load("-text", "text.txt")
  warning: load: file found in load path
  error: load: empty name keyword or no data found in file 'text.txt'
  
  x=fileread(text.txt)
  warning: load: file found in load path
  error: load: empty name keyword or no data found in file 'text.txt'
  </code></pre>
  
  <p>I have also tried simplifying the file, leaving only the coordinates and treating the file as a CSV but I keep getting similar errors.</p>
