Hi,

Does FPC have the 'NullAsStringValue' variable defined anywhere? I'm porting code from Delphi, which uses it. I had a look in my Kylix 3 help and it's mentioned there as well.

Never heard of this. Where is it supposed to be and what is it supposed to do ?

I never heard of it before either, until today. :-) In the Kylix 3 help is mentions something like this.... The value stored in the NullAsStringValue variable represents a NULL as a string. By default it is a blank string.

So I guess if you want to represent a NULL value differently, you can set it to say: '<null>'. I guess it works like the ShortDateFormat and friends variables.

I don't have Kylix or Delphi on this (home) pc, but will look at work tomorrow.

Ah, I found Kylix 3 help in home pc. It is defined in Variants unit. This is the help text.

--------------------------------------

Specifies string value of Null variants.

Unit

Variants

Category

Variant support routines

Delphi syntax:

var NullAsStringValue: String;
C++ syntax:
extern PACKAGE AnsiString NullAsStringValue;

Description

NullAsStringValue specifies the string that is the result of a conversion from a Null variant to a string type. By default, NullAsStringValue is the empty string.

NullAsStringValue is only used when the NullStrictConvert global variable is set to false.

Ok. I'll see about having it added.
Can you file a bugreport so it won't be forgotten? (you can assign it to me) I'm rather busy with the copyright issue, so better play it safe :/

Thanks Michael. I'll create a bug report. In the mean time I simply created a fpchelper.pas unit to continue my porting project.
