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
.
Although you cannot use a string such as "
61
" or "
2x+4
" in a calculation, you can convert
a string into a numeric expression by using the
expr
command.
