An increment

[system]

I'm embarrassed to ask such an apparently simple question, but here goes ...

I have the line;

for (counter = 5; counter < 17; counter ++)

Instead of increase it by 1 I want it to increase by 2. I must be becoming daft, because I can't see how to do that from the reference. I know it could be done by adding to the variable in the next line (counter = counter + 2;) but surely it should be possible within the 'for' line?

You need to write it like so:

for (counter = 5; counter < 17; counter +=2)

I'm always amazed at how fast people are to help on this forum.

Many thanks.
