I have an old program now being rewritten in visual. It uses a public variable 'gnitemnumb'. When a TABLEUPDATE() is issued the variable value is changing. When we set DEBUG on and trace the code it does not change. The code is as follows:

gnitemnumb = 1                         && variable is set
TABLEUPDATE(.t.)                          
wait window STR(gnitemnumb)            && displays a 0

The name 'gnitemnumb' is not associated with the table in any way (i.e. field name, index name) and if we change the variable name to 'gnitemnumb1' it all works fine.

Any ideas as to why this may be happening?

Thanks,
Hetty
