DATA_SEGMENT

DATA_SEGMENT

Name


      DATA_SEGMENT

Purpose


      Compute indices of data segments in an array.

Category


Calling Sequence


      data_segment, tlen, slen, [off]

Inputs


      tlen = total number of elements in array. in
      slen = number of elements in a full segment. in
      off = optional offset into array for 1st segment. in
        (default = 0).

Keyword Parameters


Keywords


        OUT=s Returned structure with follow items:
          n = number of full segments.
          ind = array of n indices of full segments.
          irem = index of remaining segment.
          lrem = # elements in remaining segment (0 if none).

Outputs


Common Blocks


Notes


      Notes: This routine gives info useful for accessing an
      array in segments. Starting at index off (def=0) read
      in slen elements and repeat n times. A remaining smaller
      segment of lrem elements starting at irem may remain.
      May also use the indices of each segment from ind to go
      directly to that segment and read in slen elements.
