while

The EGL keyword while marks the start of a set of statements that run in a loop. The first run occurs only if a logical expression resolves to true, and each subsequent iteration depends on the same test. The keyword end marks the close of the while statement.

logical expression

An expression (a series of operands and operators) that evaluates to true or false

statement

A statement in the EGL language

An example is as follows:

  sum = 0;
  i = 1;
  while (i < 4)
    sum = inputArray[i] + sum;
    i = i + 1;
  end
