Text Formatting ⇒ Skip/include line based on parameter

[pthowe]

I am trying to have a macro include an additional line only when the parameter contains the character "*". I just can not see how to accomplish this goal.

Here is a simple version of the macro:

Code: Select all

\newcommand{\formStep}[1]{
\begin{tabular}[t]{ll}  	
\ifnum{\value{#1}} %need to do if line only if "*" present in #1
	& \color{red}{* Yell UTZ} \\
	 \\
\fi
\end{tabular}
}

%code in document
\formStep{2} // no line

\formStep{2*} // line

This seems to work.

Code: Select all

%macro
\def\gobbleminus#1{\ifx-#1\else#1\fi}
\def\IsInteger#1{%
  TT\fi
  \ifcat_\ifnum9<1\gobbleminus#1 _\else A\fi
}

%document macro code
\if\IsInteger{#1} 
\else 
	&	\color{red}{* Yell UTZ} \\  	
\fi
