Hi,
Can anyone help/clarify?
I'm trying to input 3 strings via a dialog using getn and have either come across a quirk/minor bug or don't exactly understand what's going on...
The code I would expect to work is:
Create CompoundID -s 3;
%T=""; %U=""; %V="";
Getn (Compound ID 1) %%T (Compound ID 2) %%U (Compound ID 3) %%V (Enter Compound IDs);
// Use variables
CompoundID[1]$="%T";
CompoundID[2]$="%U";
CompoundID[3]$="%V";
%Z="%T";
If(%U!=""&&%U!=" ") %Z="%Z %U";
If(%V!=""&&%V!=" ") %Z="%Z %V";
SRDataPlot!compoundid.text$=" %Z"; // Keep text is not "";
This however displays " T", " U" & " V" in the dialog box.
If I don't later the values & click OK then %T,%U,%V = "".
Create CompoundID -s 3;
%T=" "; %U=" "; %V=" ";
Getn (Compound ID 1) %%T (Compound ID 2) %%U (Compound ID 3) %%V (Enter Compound IDs); seems to work OK and keeps the space but I would then have to do something like if(%T==" ") %T="";
%T=""; %U=""; %V="";
Getn (Compound ID 1) %T (Compound ID 2) %U (Compound ID 3) %V (Enter Compound IDs); displays only entries for 1st and second dialog (but no space as expected) - I then can't read these values eg %T="...".
Cheers,
Pete

Hi Mike,
That does seem to be the case, in which case (Originlab) I'd call it a minor bug.. I agree default values makes it more reliable but not ideal for the user in some cases..
Thanks for reply,
Cheers,
Pete

Hi Pete,
I agree that getn handles empty string variables awkwardly and have found that it's most reliable to start with a default value...
%T="001"; %U="002"; %V="003";
Getn (Compound ID 1) %%T (Compound ID 2) %%U (Compound ID 3) %%V (Enter Compound IDs);
That way (1) you know what will show up in the dialog and (2) the return value can be used as it was entered.
