RichEditorControl - IF command statements

I cant get this to work in one command.
Given the command is…
TdxInsertCreateIFCommand = class(TdxInsertFieldCommand)
public constructor Create(const AControl: IdxRichEditControl); override;
end;
then…
aCommand:= TdxInsertCreateIFCommand.Create(reEditor);
I have the string formatted as…
 aCommand.FieldCode:= Format(' %S { MERGEFIELD %S } = %S "%S" "%S"',"IF",Values[0],Values[1],Values[2],Values[3]]);
 aCommand.Execute;
Gives me this line for example, which on the face of it should work, but does not function…
{ IF { MERGEFIELD MyField } = 12345  "Its 12345" "Its NOT 12345" }
This is because the IF and the MERGEFIELD command HAS TO be inserted separately,
so my question is, how to do that in one go?

At present this cannot be done using a single command. The string like { MERGEFIELD MyField } is not just a text, but an RTF tag. Thus, it cannot be recognized as field code if you just type or insert it as text. As far as I know, MS Word works the same way. So, the most appropriate solution I see is to combine several actions. Attached is a small sample project demonstrating how to accomplish this task.

Hi Paulo,
Thanks alot for your efforts!
So, I seem to be able to produce something 'workable' with the attached code, which like
yours is a 'dirty' workaround for this, but maybe it will be better when the API comes out?
Please note that this contains a data entry procedure for the variables, but your should get the idea :)
However, it seems to be inconsistent with its results when connected to data and I think the
space issue is also causing problems.
For example if the field contains no data it shows an "=" symbol for some reason, and
other times just doesnt parse the IF statement.
Anyway, I hope this helps you locate a solution…

Hello Jeff,

It seems that the problem with empty values is related to the issue we are going to research in the context of the Mail Merge - The space character is not recognized ticket. Please refer to that thread to be aware of our progress.

Hi Paulo,
Im not sure if this is posible, but I have this scenario:
When using an Address block of 6 fields (lines), sometimes the 2nd (or 3rd) address line may be blank.
In this situation when merging you would get blank lines like this:
=========================
Mr Smith
1 The High Street
A Town
A County
ABC123
=========================
If would like to use a conditional "IF" to bring the line back up to the previous line
which I guess could be a BACKSPACE character code, but cant get it to work. Is this possible
or not? I have tried this below (where LINEUP would be a BackSpace code, or something that works)…
{ IF { MERGEFIELD ADDRESS2 } = "" "LINE UP CH?" { MERGEFIELD ADDRESS2 } }
The result 'should' then be…
=========================
Mr Smith
1 The High Street
A Town
A County
ABC123
=========================
What do you think?
