      Determine indentation levels of input text.


Calling Sequence

      indentation_level, txt0, txt2, lev


      txt0 = Input text array with indented text. in

Keyword Parameters


        TAB=tb number of spaces per tab (def=8).


      txt2 = Output trimmed text. out
      lev = Returned indentation level of each line. out

Common Blocks


      Notes: The lines in the input text may have various
      amounts of indentation (whitespace). The indentation
      level array, lev, will give the level for each line,
      with 0 for the least amount, 1 for the next amount,
      and so on. Make sure the indentation is the same
      for each level. It may be a mixture of tabs and
      spaces as long as the tab size is given (if not 8).
      Here is an example of indented text (txt0):
              line 1
              line 2
                line 2.1
                line 2.2
              line 3
                line 3.1
                line 3.2
                  line 3.2.1
                  line 3.2.2
              line 4
              line 5
      The lev array would be [0, 0, 1, 1, 0, 1, 1, 2, 2, 0, 0].
