Operation Notes
String constants Constant strings can be used in expressions
using quotation marks. For example:
FirstName = "Mike"
String addition Strings can be concatenated using the '+'
operator. For example:
FullName = Fir " " +
Midd " " + LastName
String subtraction String1-String2 results in an integer in the
range of
–255
to
+255
.
String conversion to/from Numerics Conversion of strings to numerics and numerics
to strings is done automatically when an
assignment is made from a string to a numeric
or a numeric to a string, if possible.
