Subject: | Re: FLASH: anyone written an arctangent function for flash? |
From: | John Andrew Morrison |
Date: | Fri, 30 Jun 2000 22:18:40 +0100 |
Maybe I'm naive, but wouldn't it be better to use the
loadvariable capabilities to run a perl, PHP or ASP
script which has the functions built in?
Thanks,
John
