I'm maintenancing a program in fox5. Once in awhile the append does not work and we lose data. Here is the code:

use lifs
t1b = flock()
append from lifcdprt
set talk off
close databases

Now I've done a little research and learned that an append does not need an flock() but wasn't sure if this could be causing the problem. If the code is correct, is there a way to check if an append is successful?

Thanks,
Sunshine
