Hi again Wolfgang and Peter,
The solution you provided to my problem is great but has a small issue…
Considering the definition
\define[3]\RandomCoeff{%
\setvalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}
}
after saying
\RandomCoeff{Alpha}{1}{10}
one gets \CoeffAlpha, but if I use several times \CoeffAlpha, it takes a new
value each time, an effect which is undesirable in what I am willing to do.
Is there a way to somehow « freeze » the value of \CoeffAlpha once it is
defined?
Best regards: OK
PS: here is the complete example:
\define[3]\RandomCoeff{%
\setvalue{Coeff#1}{\ctxlua{tex.print(math.random(#2,#3))}}
}
\starttext
\RandomCoeff{Alpha}{1}{10}
\RandomCoeff{Beta}{10}{100}
\CoeffAlpha
\CoeffBeta
\CoeffAlpha
\CoeffBeta
\stoptext
