This error comes up once in a while in the exe I inherited. Although I know what it means I don't understand reads well enough to know how to avoid the error. I am using foxprolan 2.0 for dos and have had no formal training with the language, just what I have read in books. I ammore familiar with oop database programming. The way the system was set up is to keep opening a window to do some natural progression of an order entry. Can anyone explain to me how to keep the read level below the maximum? It would be much appreciated as there is little help around here for this older version of foxpro. Thanks.
