Excerpt from Automatic Data Processing Program for Marine Synoptic Radio Weather Reports The perforated tape is fed into an ibm 047 tape-to-card key punch machine to convert each ship's weather observation to standard data card format. These data cards are then accumulated each month for processing. The data are presorted by octant and longitude into 10-degree wide strips to facilitate proc essing by the machine and to provide a logical output format. The information on each of the sorted cards is then loaded onto magnetic tape for high-speed input to the computer. The basic steps are schematized in figure 3.
