Required Argument

stream-variable

specifies a stream variable, which is a temporary item store that contains output.

Tip:If you assign the name of a memory variable to stream-variable-name, then the stream variable resolves as the value of the memory variable. For example, the following partial program uses the memory variable $MyStream as a stream variable:

set $mystream 'test';
 open $mystream;
 put 'The memory variable $mystream is being used as a stream variable';
 close;

Therefore, the following statements are equivalent:

put $$test;
 putstream $mystream;
 putstream test;

The following statements are also equivalent:

unset $$test;
 delstream $mystream;
 delstream test;
