behavior of [! !]

Fri, 01 Aug 2003 19:52:46 -0700

Was reading through the documentation, and don't see too much detail on the exact differences between [! !] and [- -]. I see that [! !] runs the code block once. But, it's unclear what "once" means.

Here's a little test I did:

test2.epl:
<HTML><HEAD></HEAD><BODY>
[- $a = 0 -]
[! $a++; !]
a = [+ $a +]<br>
<FORM ACTION="test2.epl" METHOD="POST">
<INPUT TYPE="SUBMIT" VALUE="Submit 2">
</FORM>
</BODY>
</HTML>

Is the [! !] block run the first time the page loads, and therfore not run again when you click refresh?
When I use [! !] to define a subroutine, where is the subroutine stored?
[- -] blocks allow me to use variables created in them later in the page. Why does [! !] do not?


Thanks!
