The original definition given was this:
- An undefined variable in a computer program is a variable name that is called by the program but which has not been previously assigned a value by that program.
I think that would describe an "uninitialized variable". For example,
// C int x; printf("%d", x); // x is declared but uninitialized
// Java Frame x = null; x.show(); // x is declared but set to null
Some clarification may be needed of the terms
- undefined variable
- undeclared variable
- uninitialized variable
- NULL (C), null (Java(, nil, or undef (Perl) as in reference or pointer type.

- I totally agree. "Definition" == assignment. This article describes, as its first sentence even suggests, undeclared variables. --pfunk42 11:41, 9 November 2006 (UTC)
