Try this:
| Code: | %%input = "hello this is a url http://www.server.com enjoy..."
if @greater(@pos(http://,%%input),0)
%%output = @substr(%%input,@pos(http://,%%input),@len(%%input))
%%output = @substr(%%output,1,@pos(@chr(32),%%output))
end
info %%output |
You can change @chr(32) to every ASCII code you'll need as the end of the URL...

on these line, when links are clicked all i get it a message form windows telling me it cant open h.

Just extend it a little.Check if the substr after http:// is www if so include else U know. That's all.

DW, that's because there isn't a @chr(32) after the http://. The next code checks if there is. If there isn't such a character, it will take the whole string which is left.
| Code: | %%input = "hello this is a url http://www.server.com"
if @greater(@pos(http://,%%input),0)
%%output = @substr(%%input,@pos(http://,%%input),@len(%%input))
if @greater(@pos(@chr(32),%%output),0)
%%output = @substr(%%output,1,@pos(@chr(32),%%output))
end
end
info %%output |
