Description | Use the for keyword to specify a fixed number of iterations of a loop. The number may be a literal number, or an expression that evaluates to a number. (If the number is not an integer, it is rounded to the nearest integer.) Either way, the number is evaluated when the repeat control structure is entered, and is not re-evaluated as a result of statements in the loop. For example, if the repeat control structure begins with the line
then this number is evaluated as of the start of the loop, and the number does not change even if the statements in the loop create or delete cards. For this reason, use caution when using the for keyword with an expression : do not assume the expression will have its current value when the statements inside the loop are executing. |
