A way to check if record field is already set

Hi,

I wonder if there is any way to check if record field is already set.

For example, I try to access c$http$host for every HTTP request, and in some cases when the host header is empty I get an exception.

I need a way to check if the feild is set before I try to check it.

Thanks,

Omer!

“?$” will check if a value exists for any field. For your example, put $http?$host in the script before you try to process the host field.
