system, the LEO system is started and functions are selected and
processed. This interactive procedure is initiated from a terminal
with either printer or screen display.
Data retrieval function
This function is initiated Interactively and then completed in
batch mode. An interactive convorsational procedure prompts the user
for information identifying a specific subset of the data base. In
batch mode, data arc retrieved from tape and copied to an exclusively
named user disk file to be used for further processing la the Data
Reporting Function.
Data reporting function
This function prepares and displays statistical reports. It may
be run in either interactive or batch mode. If run interactively,
the user may view the reports at his terminal. If run in batch mode,
the reports are processed independently of the uaor's session and
printed at a high-speed printer.
The Data Reporting Function offers a library of statistical
programs to produce various reports. Each report Is headed by the
report title, site name and number, and latitude/longitude. All
reports may be displayed on the terminal's screen or printer or
printed at a remote high-speed printer. The retrieval system
restricts terminal report output to 22 lines. This programcontrolled
Interrupt offers time to view the report and an oppor
tunity to continue or stop the report display. The following are the
reports available to users of LEO data.
1. Dally LEO observatons (Figure 2) - a formatted listing of the
LEO data set. Data parameters provided in the report are surf
conditions, local winds, littoral currents, and foreshore slope.
These parameters are displayed by date and time of observation.
