GRP: Observation Group Name

This record specifies a group name (used in printing various information concerning observations) for a set of observations. Group names provide a means for searching in output files for a specific group of observations.

All observation after a GRP record, and before the next GRP record, will be assigned the group name on that record. If the group name field (columns 7-70) is blank, a group name is not assigned to the observations following the GRP record.

See General Layout of Observation Groups for more information.

The format of the GRP record is as follows:

Columns 002-005: GRP
Columns 007-070: Group name (any text)
