String Expressions
String expressions are constructed from string variables, string
constants. and function references using the operation for
concatenation
(&). The operation of concatenation allows you to
combine strings together. All functions referenced in a string
expression must be either functions supplied in
TI BASIC (see
Built-In
String Functions) or defined by a DEF statement and
must have a
string value, If evaluation of a string expression
results in a value which exceeds the maximum string length of
255
characters. the string is truncated on the right and the
program continues running. No warning
is given.
Note that all charaL:ter~ illduueu ill a ~LlilJg eXVle~~iuu are
always displayed on the screen exactly as you enter them.
