how to test the type of a variable

Postby melamel » Tue Jun 21, 2016 5:42 am

Hello,
I want to test the type of a program argument to see if it's a date or not, just to prompt a message error if it's not a date. How can I do this please ? which function can give me the type of a variable?
Thank you in advance !
