String Operations
Strings are used to enter and display text characters. You can type a string directly, or
you can store a string to a variable.
How Strings Are Used
A string is a sequence of characters enclosed in "quotes." In programming, strings allow
the program to display information or prompt the user to perform some action. For
example:
Some input commands (such as
InputStr) automatically store user input as a string and
do not require the user to enter quotation marks.
A string cannot be evaluated mathematically, even if it appears to be a numeric
expression. For example, the string "
61" represents the characters "6" and "1", not the
number
61.
