Colleagues,

I've never seen such behavior: some fields are nullified upon a cursor's being saved into a DBF file on disk!
Here's what's going on:
I have a cursor, populated in the code (with INSERT INTO C_CURSOR FROM MEMVAR) in a cycle;
I set a STEP ON after the end of that cycle to check the contents of one particular field;
Checking this field (numeric) after cycle's completed - the value is correct (non-zero);
Some additions to this cursor (client's store's attributes) in the code, check this field again - the value is still correct (non-zero);
I COPY TO (SomePath\C_COPY.DBF), checking this field again (right after that command) - bloody hell, it's Zero! :-@
As well as couple other fields that weren't zero in the cursor before copying it into a DBF! :-@:-@

Here's the actual code:

***** Debug *****
IF _VFP.StartMode==0
   SET STEP ON
ENDIF
*****************
SELECT CO_STATE && Just in case
** Preserve the resulting cursor
COPY TO (m.gcCompanyPath + [CO_STATE.DBF]) ALL

Whatever I tried - the result was the same: this particular field turns to zero at the moment it's been copied into a DBF file on disk.

Any idea why this might be happening, and how I can fix it?

AHWBGA!

Regards,

Ilya
