d) Boolean parameters
A Boolean parameter represents a true or false binary condition, which can only have four possible
values.
Boolean parameter examples:
ON Logical true
OFF Logical false
1 Logically true
0 Logically false
e) String parameters
String-type parameters allow ASCII strings to be sent as parameters. Single quotes and double quotes
are used as separators.
Examples of string parameters:
‗This is Valid‘ ―This is also Valid‖ ‗SO IS THIS‘
f) Real response data
Most of the test data are of real number type, and their formats can be basic decimal notation or
scientific notation, which are supported by most advanced programming languages.
Examples of real number response data:
1.23E+0
-1.0E+2
+1.0E+2
0.5E+0
0.23
-100.0
+100.0
0.5
g) Integer response data
An integer response data is a decimal expression of an integer value containing signed bit. When
querying the status register, most of the response data returned are of integer type.
Examples of integer response data:
0 Sign bit optional
+100 Positive lookahead allowed
-100 Negative lookahead allowed
256 No decimal point
h) Discrete response data
Discrete response data are basically the same as discrete parameters, only that the return format of
discrete response data is only a short form in uppercase.
Examples of discrete response data:
