#119 RLFI issue with binomial

[Avery Laird]

Reduce (Free CSL version, revision 5227), 01-Jan-20 ...

1: load rlfi;

2: on latex;
\documentstyle{article}
\begin{document}

3: binomial(a,b);

***** Missing evaluation for type tex

This seems to be exclusively an issue with the RLFI package. Both PSL/CSL have the same behaviour

[Eberhard Schruefer]

Actually, rlfi doesn't know about binomial. If you read the appended code into your terminal and then use rlfi does this work for you?

put('tex,'evfn,'texevfn);

symbolic procedure texevfn(u,v); reval1(cadr u,v);

symbolic procedure binomprla(u,p);
   begin
     prin2la "\binom";
     prin2la "{";
     maprintla(car u,0);
     prin2la "}{";
     maprintla(cadr u,0);
     prin2la "}"
   end;

put('binomial,'laprifn,'binomprla);

That did the trick. Thanks!

Thanks for checking. It will be included in the next snapshot.
