Section 5 Command Descriptions

5.2

5.2 Command Description Format

Each command description is divided into several areas:

5.2.1 Syntax

The syntax section of the command description describes the proper

command syntax which must be sent to the Micro488/EX using the IBM

BASIC

PRINT#

command, or its equivalent in other languages, to the

COM port. The following conventions are used in the syntax descriptions:

No command, along with its options, may be more than 127 characters

long. The

data

part of the

OUTPUT

command is not constrained by this

length. It is, however, limited to the available USER MEMORY. The

OUTPUT #count;data

may contain be as long as necessary. Refer to

the

OUTPUT

command for more information on this.

Items in capital letters, such as

ENTER

OUTPUT

must be used

exactly as stated. Abbreviations may be used with some commands to

reduce serial transmission traffic.

Items in lower case, such as

addr

count

represent parameters

which must be substituted with an appropriate value.

Blank spaces in commands are generally ignored. Thus,

LOCAL

LOCK

OUT

is the same as

LOCALLOCKOUT

. Spaces are not ignored in four

places: the

data

part of an

OUTPUT

command, within quoted strings in a

SEND

command, after an apostrophe (

) in a terminator specification

(

term

), and after the semi-colon following the

command.

The number sign character (

) and the semi-colon (

;

) must be present

exactly as shown. A comma (

) represents an address separator. The

oblique or slash character (

) or period (.) may be used in its place as the

address separator.

Optional semicolons (

[;]

) may be used, if desired, for consistency

with other IOtech products.
