Learn How To Use It In Minutes.
Since the Professional-488 talks the established IEEE
control language, you probably already know how to use it! A
good way of learning how to use the Professional 488 is inter-
actively from the keyboard of your Personal Computer using the
GPIBTALK suit of programs. Included on the Professional 488
system disk is the source code, and the ready run versions of,
GPIBTALK in each of four languages. ATALK in Assembly
language, CTALK, PASTALK and GPIBTALK in GW-BASIC
and BASICA. These powerful programs are a menu driven sys-
tem that allows you to send IEEE commands, transmit and
receive data from your bus devices and check the status of the
GPIB interface bus, all at the touch of a single key. In this way
the user can get a good feel of the power and ease of use of the
Professional 488 command language in a very short time. Most
IEEE equipment includes worked examples that are virtually
word for word PRO-488 commands!

PRO-488 Command Summary.
The basis of the PRO-488 system is an intelligent
command handler. Data written to the "IEEECTRL" file is
treated as an Ascii string containing IEEE bus keywords and
parameters. These keywords are commands to perform Serial or
Parallel Polls, send any IEEE bus commands or specify the
timeout period, etc etc.
The command interpreter checks the syntax of your IEEE
string and performs the appropriate IEEE actions. If a syntax
error is detected the precise location of the error is noted and a
flag is set. Merely checking the error flag informs you whether
