GETRUN

Name


      GETRUN

Purpose


      N'th run of consecutive integers from a given array.'

Category


Calling Sequence


      w2 = getrun(w, n, [m])

Inputs


      w = output from where to process. in
      n = run number to get (first = 0 = def). in
      m = optional last run number to get. in

Keyword Parameters


Keywords


        LOCATION = l. Return run n start location.
        /LAST means n is offset from last run. So n=0 gives
          last run, n=-1 gives next to last, ...
          If n=-2 and m=0 then last 3 runs are returned.
        /LONGEST returns the longest run. n returned, m ignored.

Outputs


      w2 = returned run or runs. out

Common Blocks


Notes


      Note: Getrun is meant to be used on the output from where.
            if m > n then w2 will be a string of runs from run n to
            run m. If no m is given then w2 will be a single run.
            If n<0 returns runs starting at run abs(n) to end of w.
            If n is out of range then a -1 is returned.
            See also nruns.
