Need help with - howto find struct field

[Jan Kowalski-3]

Hi, I try to convert string to structure field. As example:

 function getRepF(argo,argn: string): boolean;
 begin
 ...
       dataA.'argn':=argo;
 ...
 end;

argn is a string with name of structure (dataA) field. Is there any
way to do that ? somethink like FindStructField ?

Please help!

Regards
faber

In general: no. In compiled languages, identifier names are generally
eliminated in the compilation process.

There are remote cases possible for classes (RTTI/introspection), but these
are special cases. See the examples for e.g. unit typinfo.
