Only if you write beyond the bounds of the record. And of course, the record must be "loaded and locked" before you write to it. >as I try using DmWrite b4, but i got bus error Did you try to DmWrite more bytes than the record is in length? If so, you need to resize the record prior to writing the additional bytes. You might want to read the Data Manager chapter of the Palm OS Reference for more info, and do a search on "DmWrite" in the Companion Guide for a couple code snippets.
