Chapter 11 Loops and Charts

The For Loop executes the diagram inside its border a predetermined

number of times. The For Loop has two terminals, explained below.

Count terminal (an input terminal)—The count terminal specifies the

number of times to execute the loop.

Iteration terminal (an output terminal)—The iteration terminal contains the

number of times the loop has executed.

The For Loop is equivalent to the following pseudocode:

For i = 0 to N-1

The following illustration shows a For Loop that generates 100 random

numbers and displays the points on a chart.

Numeric Conversion

Until now, all the numeric controls and indicators you have used have been

double-precision, floating-point numbers represented with 32 bits. G,

however, can represent numerics as integers (byte, word, or long) or

floating-point numbers (single-, double-, or extended-precision). The

default representation for a numeric is a double-precision, floating-point.

If you wire two terminals together that are of different data types,

G converts one of the terminals to the same representation as the other
