NOTES FOR EDICT USERS
CRIMSON USER MANUAL - MODULAR CONTROLLER
You will notice that the for statement contains three distinct elements, each separated by
semicolons. The first element is the initialization step, which is performed once when the loop
first begins; the next is the condition, which is tested at the start of each loop iteration to see if
the loop should continue; the final element is the induction step, which is used to make a
change to the control variable to move the loop on to its next iteration. Again, remember that
if you want more than one action to be included in the loop, include them in curly-brackets!
THE DO LOOP
This type of loop is similar to the while loop, except that the condition is tested at the end of
the loop. This means that the loop will always execute at least once.
The architecture of the do loop statement is as follow…
do {
action1;
} while ( condition );
The example below shows the example from above, rewritten to use a do loop…
int i:=0, t:=0;
do {
t += Data[i];
} while( ++i < 10 );
return t;
LOOP CONTROL
Two additional statements can be used within loops. The break statement can be used to
terminate the loop early, while the continue statement can be used to skip the balance of the
loop body and begin another iteration without executing any further code. To make any sense,
these statements must be used with if statements to make their execution conditional. The
example below shows a loop that terminates early if another program returns true…
for( i:=0; i
