Simkin While Statement

This statement allows you to execute a series of other statements until an expression is true.

The format of the statement is:

while (<test-expression>) {
 <statements...>
}

For example:

i=0;
while (i lt 3) {
  trace(i);
  i=i+1;
}

will print:

0
1
2

Note: you have to use the braces "{" and "}" to surround the statements after the while clause.
