while
while — iterates, evaluating a statement.
Syntax
while (condition) statement
Arguments
- condition
Any Gamma or Lisp expression.
- statement
Any Gamma or Lisp statement.
Returns
The value of condition at the final
iteration.
Description
This function iterates until its
condition evaluates to nil, evaluating the
statement at each iteration. The
condition is evaluated before the
statement, so it is possible for a
while loop to iterate zero times.
Example
Gamma> x = 0;
0
Gamma> while (x < 5) { princ (x, "\n"); x++; }
0
1
2
3
4

Gamma> x;
5
