By writing \ifnum cond1 and cond2, the compilation is successful but the generated document is conceptually invalid.

If possible, how to specify logical connectives?

Please elaborate on your meaning of "conceptually invalid". – Werner Nov 09 '11 at 00:45

Hi juliohm, welcome to TeX.sx! I think you might need to add some more information to your question: What do you mean by "conceptually invalid"? What are you trying to achieve? What is the role of TikZ in this (you can use \ifnum statements inside a tikzpicture)? – Jake Nov 09 '11 at 00:47
Hi @Werner, i mean cond1 holds and cond2 don't. – juliohm Nov 09 '11 at 00:47
Hi @Jake, thank you. Yes, we can use \ifnum inside a tikzpicture environment. – juliohm Nov 09 '11 at 00:49

@juliohm: You can't logically connect two conditions using \ifnum; instead you will have to nest your statements: \ifnum 1<2 \ifnum 2<3 Success! \fi \fi. Could you elaborate on how this relates to TikZ? – Jake Nov 09 '11 at 00:54

@juliohm: ...and to use an OR condition, you could nest them using \ifnum 1<2 Success! \else \ifnum 2<3 Success! \fi \fi. – Werner Nov 09 '11 at 00:55

Thank you again Jake, i'm not experienced with TeX, i was thinking the \ifnum command was part of TikZ/PGF package. – juliohm Nov 09 '11 at 00:59
@Jake: Write up some conditionals (AND and OR) as an answer using \ifnum and either @juliohm or you edit your question to remove the TikZ/PGF reference. – Werner Nov 09 '11 at 01:01
@Werner, it's done. – juliohm Nov 09 '11 at 01:05

@GonzaloMedina: Good find! I think it's best to close this questino as a duplicate, instead of adding an answer. – Jake Nov 09 '11 at 01:27
@Jake: I'm sorry I didn't find that question before... I see that you've already deleted your answer, so I agree. – Gonzalo Medina Nov 09 '11 at 01:56
