Program Codes 444

Non – Printing Characters

Non Printing Characters are supported through use of a pair of two printing codes to equal the non-

printing code. This pair of characters is retained in the program code but sent as single 8-bit code

when transmitted.

There are three types of character pairs and each performs a different operation based on the first

character of the pair. This produces a single modified character for transmission.

Character Options

1) The “&” two-character pair clears the 0x40 bit from the 2

character code value.

2) The “!” two-character pair clears the 0x40 bit and sets the 0x80 bit set in the 2

character

code.

3) The “$” two-character pair clears the 0xC0 bit in the 2

character.

To transmit the single character with a value 0x01, use the two character sequence ”&A”. This

converts the “A” value of 0x41 to 0x01 by clearing the 0x40 bit. To transmit 0x81, use “!A” or to

transmit)xC1 use “$A”.

Exceptions / Additions

As the “&”, “!” and “$” are used as key indicators for the Non-print characters, there is a special format

used when these characters are used as a print character in the message text. Simply use the

character twice. “&&” = “&”

The ESSI style part program uses several unique characters which requires special two character

codes to be used. For example, the message code “&K” in the part program will transmit the code

value of 0x2B which is the ASCII code for the plus sign (+). In order to send the + character the code

“&K” must be used.

The following are unique codes used in WORD ADDRESS and ESSI programs

Code Code Value Description

&‟ 0x20=space At end of ESSI program

&h 0x28 = “(“ To transmit “(” from WORD ADDRESS program

&i 0x29 = “)“ To transmit “)” from WORD ADDRESS program

&? 0x7F = DEL Non-printable DELETE code

&K 0x2B = “+” To transmit “+” from ESSI program
