New Era -1363 Error

We get a lot of -1363 memory errors in New Era. Seems to be caused if you try and assign nothing to a variable. This might be as a result of trying to get data from an empty superfield or the results of an sql query once notfound has been reached. It is as if New Era actually does assign nothing to the variable rather than a zero length null terminated string. Anyone else have this problem and is there an easy solution other than checking for null before you assign? Ian. ps. After programing other gui's I think New Era is great.
