- An actual piece of data, in contrast to all the variables, references, keys, indexes, operators, and whatnot that you need to access the value.
- A named storage location that can hold any of various kinds of value, as your program sees fit.
- The interpolation of a scalar or array variable into a string.
- Said of a function that happily receives an indeterminate number of actual arguments.
- Mathematical jargon for a list of scalar values.
- Providing the appearance of something without the reality, as in: virtual memory is not real memory. (See also memory.) The opposite of "virtual" is "transparent", which means providing the reality of something without the appearance, as in: Perl handles the variable-length UTF-8 character encoding transparently.
- A form of scalar context in which an expression is not expected to return any value at all and is evaluated for its side effects alone.
A "version" or "vector" string specified with a
vfollowed by a series of decimal integers in dot notation, for instance,
v1.20.300.4000. Each number turns into a character with the specified ordinal value. (The
vis optional when there are at least three integers.)
