HP OpenVMS Systems Documentation

Signals the end of a data stream when a command or program is reading data from an input device other than an interactive terminal.

Format

$ EOD

Parameters

None.

Description

The EOD (end of deck) command in a command procedure or in a batch job does the following:

• Terminates input data lines that begin with dollar signs ($). The DECK command indicates that the following lines begin with dollar signs and should be interpreted as data, not as commands; the EOD command indicates the end of the data lines.
• Terminates an input file if multiple input files are contained in the command stream without intervening commands. The program or command reading the data receives an end-of-file (EOF) condition when the EOD command is read.

The EOD command must be preceded by a dollar sign; the dollar sign must be in the first character position (column 1) of the input record.

Examples

$ CREATE WEATHER.COM 
$ DECK 
$ FORTRAN WEATHER 
$ LINK WEATHER 
$ RUN WEATHER 
$ EOD 
$ @WEATHER 
      

In this example, the command procedure creates a command procedure called WEATHER.COM. The lines delimited by the DECK and EOD commands are written to the file WEATHER.COM. Then the command procedure executes WEATHER.COM.

The program MYPROG requires two input files; these are read from the logical device SYS$INPUT. The EOD command signals the end of the first data file and the beginning of the second. The next line that begins with a dollar sign (a PRINT command in this example) signals the end of the second data file.
