Hi,
Please note that this can be used only for temporary indexes.
When index is reopened then it needs valid key and for expressions.
It means that we create corrupted indexes in such way.
I'm sure I do not reopen tags with empty key expression. We can add key
expression check for expression

Hi,
1) negative julian dates
SET(4, "-mm-dd")
dDate := CTOD("") - 1
? dDate // Clipper: "1449-02-15", Harbour: "- - "
...
So at beginning we should not expect that the date converted to
string should will be non empty if date is not empty. It isn't
even with Clipper.
? ct
Hi,
Index is not created due to invalid index key expression: ""
Current DBFCDX detects it and do not create index but RT
error is not generated. Clipper does not validate key expression.
I do not remember why exactly we added stringed key expression
validation but it was done in last few months

Hi,
my friends showed a few more Clipper incompatibilites.
1) negative julian dates
SET(4, "-mm-dd")
dDate := CTOD("") - 1
? dDate // Clipper: "1449-02-15", Harbour: "- - "
I would suggest to fix a code for samples like this, but sometimes this
Harbour behaviour can lead to
