NOTES: [1] Columns 27-30, 41-50, 61-70 have different meanings for different
types of data. However, digits specified in these columns result
in actions being taken by the program in the same manner as
indicated for column 26.
[2] If PREPRO is intended to apply to all data a PREPRO
card should preceed all SELECT cards otherwise PREPRO
applies only to its preceeding SELECT card in the setup.
IF CARD OMITTED: The absence of a PREPRO card is an indicator that the
observation data is to be used as it appears on the
input data file.
With a blank PREPRO card corrections will be applied
as indicated by the PREPRO word on all header records.
