Example

This example was taken from the 1980 United States Geological Survey implementation of the Network-Day Tape format[3]. It has not been tested before inclusion here.

subroutine prbuf(idata)
#
# (A long documentation comment - stripped from the example in the Formats Wiki)
#
integer*2 idata(1) # DATA RECORD - INPUT
# SET TO HOLD 16000 BITS OF TAPE INPUT RECORD
#
  integer*2 i
  integer*2 j
  integer*2 ibuff(80)
#
  do i = 1,25 {
    call getlin(idata, i, ibuff)
    write(6, 10) (ibuff(j), j=1,80)
10    format(1x, 80a1)
 }
#
  return
#
end
