This section describes all the BASIC keywords provided by the HP 8271 8A Expansion Pod. First, the
name of the keyword is given, followed by the category of keyword (high-level modem, electronic disc, or
bar code) and whether the keyword is a function (returns a number or string) or a statement (performs an
operation but returns nothing). The next line lists the syntax of the keyword and its expected parameters.
One or more examples of the use of the keyword follows. The description of the keyword appears next,
and includes any cautions, set off by bullets, that should be observed when using the keyword. Finally, a
list of possible errors that may be reported by the keyword is given.
Notes on syntax: Optional parameters are surrounded with brackets ([]).
>::t'lEt'l
is the device code for the
electronic disc.
The syntax of path names, locations, and directories is described in "Electronic Disc
Software" in Section 2.
Notes on error n urn bers: Error n urn bers of 1 50 or greater are those reported by the HP 827 1 8A, and are
described in appendix D, "HP 8 2 7 18A Errors and Responses." The other error n urn bers are included for
completeness, but are described in the
HP-75 Owner's Manual.

with the specific file on the electronic disc and sets the
corresponding data pointer to the first line of the file. A new file is created on the electronic disc if the
named file doesn't exist. If the file type is not specified, the default is BASIC .

within the file hierarchy, execute
