OBEY Command The OBEY command executes a series of Exchange/SNA commands read from a file.

O[BEY]

command-file

is the file containing the Exchange/SNA commands that you want to execute. The

commands in the file are read and executed until the end of the file is reached, at

which point control returns to the Exchange/SNA command interpreter and you

can again enter commands interactively.

The file can be an unstructured disk file, an EDIT-format file, a device file, or

another process. The maximum record length is 130 characters.

If you omit the volume name, your current default volume is used. If you omit

both the volume and subvolume names, your current default volume and

subvolume are used.

Considerations The OBEY command executes a sequence of Exchange/SNA commands read from the

specified file (the command file). By placing a commonly used sequence of commands

in a file, you can execute the complete sequence of commands with a single OBEY

command.

You can use the OBEY command within a command file. The depth to which you can

nest OBEY commands is limited only by available memory.

Error Handling

If a command from the command file produces an error, an error message is displayed

and execution continues with the next command from the command file. If the

following commands are dependent on the command that failed, the following

commands also fail. For example, if a CONNECT command fails, all subsequent

SEND and RECEIVE commands also fail.

BREAK Key

If you press the BREAK key while a command file is executing, execution is suspended

and control returns to the command interpreter. When control returns to

Exchange/SNA, the command file continues executing from where it left off.

Example This example shows the OBEY command:

>o ex02

COMMENT - reconnect to $SNAX1 line server

SET NAME $SNAX1

CONNECT !

SNCI37 CONNECTION ESTABLISHED WITH SERVER '$SNAX1'(7,51) ON SYSTEM \SNAX
