load_env ARRAY

Well you could set a flag via a hidden form variable and then read that via
var get formvariablename
Or use javascript onclick() that will lead to an XMLHttpRequest, but AJAX
is a bit beyond what you're looking for I think :)
There is 1 submit button per form. If you want multiple buttons then you
need to instantiate multiple forms.

form.html:
<form action="nextpage.rvt" method="POST">
Enter your Name here:
<input name="name" length="25">
<BR>
<input type="hidden" name="buttonpressedflag1" value="1">
<input type="submit">
</form>
nextpage.rvt:
<?
load_env ENV
set name [ var get name ]
set flag [ var get buttonpressedflag1 ]
puts "Hello $name!<BR>"
if {$flag == 1} {
puts "also flag was tripped"
}
puts "<BR>"
puts "Script name: $ENV(SCRIPT_NAME)"
?>
