Problem sending Strings using SendMessage / PostMessage

I have been trying to send Text from one Powerbuilder application to
another, but haven't had much luck.

I use the SendMessage and PostMessage API calls, and Pass a String
value, but when the receiving application gets the message, it only
receives a pointer to the passed string.

Can you please help me in working out how to find this String
referenced by the pointer?

Get the value by using the "address" format qualifier, as such:

ls_TextFromPointer = String(ll_PointerValue, "address")


The "address" format for the String function isn't documented very well
in PB, btw.
HTH,
