Hello again!
Today I'm trying a lot of new (to me) things...
This time, a macro with optional arguments and \if...argument :
\def\SkillField{\dodoubleempty\doSkillField}
\def\doSkillField[#1][#2]#3{\bTR\bTD #3
\iffirstargument\hfill (#1)\fi % don't print when no optional
argument
\eTD \bTD
\ifsecondargument % if second optional arg is provided
\definefield[#2][line][Skill][#1]\field[#2]
\else % if no second optional arg
\definefield[#3][line][Skill][#3]\field[#3]
\fi
\eTD\eTR}
e.g.
\SkillField[+8][Aergern]{Ärgern} % works
\SkillField[+1]{Labern} % does nothing instead of "else"
\SkillField{Testen} % does "\hfill (#1)", but should do nothing
Apparently, the \if...argument ... \else don't work as they should.
Where's my mistake?
Grüßlis vom Hraban!

Hi,
There is interference with the \bTR macro. It works fine with all
TABLE commands removed. The table macros like \bTR and \bTD
themselves use \dodoubleempty.
Greetings, Taco
