There are three commands that deal with string variables, or messages. The first of these commands is the
VARS
command. This command sets a string variable equal to a specific message (e.g.,
VARS1="Enter
part count"
). The message must be placed in quotes for it to be recognized. The same can be said for the
WRITE
and
DWRITE
commands. Their messages must also be placed in quotes (e.g.,
WRITE"Today is the
first day of the rest of your life"
).
Syntax possibilities:
VARSn="<message>"
where
n
equals the string variable number
WRITE"<message>"
DWRITE"<message>"
There are three ASCII characters that cannot be used within the quotes (
:
,
"
, and
;
). These characters can
be specified in the string by using the backslash character (
\
) in combination with the ASCII decimal value
for the character. For example, if you wanted to display the message
"WHY ASK WHY"
in quotes, you would
use the following syntax:
WRITE"\34WHY ASK WHY\34"
.
An ASCII table is provided in Appendix B . Common characters and their ASCII equivalent value:
Character Description ASCII Decimal Value
<lf>
Line Feed 10

The ASCII Character Designator (
\
) operator is used to place a character in a string that is normally not
represented by a keyboard character. The (
\
) operator can be used within the
VARS
or the
WRITE
commands. The syntax for the (
\
) operator is as follows:
WRITE"\<i>"
, Where
<i>
is the ASCII decimal equivalent of the character to be placed in the string.
VARS1="\<i>"
, Where
<i>
is the ASCII decimal equivalent of the character to be placed in the string.
There are three ASCII characters that cannot be used within the quotes (
:
,
;
, and
"
). These characters must
be specified in the string by using the backslash character (
\
) in combination with the ASCII decimal value
for the character.
