This statement repeats a series of statements, incrementing or decrementing an index variable.

This statement has the following syntax:

The for statement, also called the for loop, repetitively executes the series of statements in the statementlist between the do and endfor keywords. The specified indexvariable is incremented (if to is specified) or decremented (if downto is specified) after each iteration of the series of statements. The series of statements is executed until the indexvariable exceeds (to) or becomes less than (downto) the specified endexpression. This test is performed before each iteration (thus, it is possible for no iterations to be executed). The specified endexpression is re-evaluated for each test.
