Dear list, I have the following document: \mainlanguage[es] \starttext \startTEXpage[offset=1em] \dorecurse{27}% {\def\abcd{\convertnumber{a}{\recurselevel}}% \dorecurse{27}% {\abcd\convertnumber{a}{\recurselevel} }\par} \stopTEXpage \stoptext I want to test all lowercase-letter pairs in Spanish. Excuse me for my missing programming notions. For the sample above, I would need a command that behaves as a variable when defined, but as a constant when invoked. Is there any way to achieve that without using counters? Sorry if there is too much nonsense in the previous paragraph. But I need to know how to do it for another example too. Many thanks for your help, Pablo -- http://www.ousia.tk
