AB,
The only way to guarantee that B executes after A is to have
B's input depend on A's output. Since WriteImage has no outputs,
it gets a little complicated - you have to put WriteImage inside
a macro, and have the macro produce an output (e.g., the image
file name) that can flow to the System module.
Cheers,
Joel

I am fairly new to openDX, but using the visual program editor I've
managed to do some fairly neat stuff. However, I have a problem with
the order in which the commands are carried out on a given page. In my
particular example I'm using writeImage to write an image file to disk
and then modifying it using the System command. The problem is, the
System command executes before writeImage and so there's no file to
operate on. I'm sure this is an extremely simple problem, but I haven't
yet figured it out.
Any help appreciated.
