Single
quote is used
in C and derived languages to introduce
a single character
literal value which is represented
internally by its ASCII code.
In the
Unix shells and
Perl single
quote is used to delimit strings
in which
variable substitution is not performed (
in contrast to
double-quote-delimited strings).
Single
quote is often used
in text for both open and close
single
quotation mark and apostrophe. Typesetters use two
different symbols - open has a tail going up, close and
apostrophe have tails hanging down (like a raised
comma).
Some people use
back quote (') for open single
quotation
mark.
