My problem is: When I uncomment the commented part in the definition of the command (ifnum#1>9 …) and I type as an argument the letter "a", I get an error. But when I comment this part, I don't.



My question is: How can I fix this error?

    a is not a number, you should use something like sieben{1}. If you want the argument to be a hexadecimal you should use ifnum"#1 and sieben{A}.

My problem is: When I uncomment the commented part in the definition of the command (ifnum#1>9 …) and I type as an argument the letter "a", I get an error. But when I comment this part, I don't.



My question is: How can I fix this error?

    a is not a number, you should use something like sieben{1}. If you want the argument to be a hexadecimal you should use ifnum"#1 and sieben{A}.

Most likely I do not understand your question. But I'd like to argue that one should first check if the argument is a number (I only check if it is an a but this could be extended) and then use ifcase for the integer cases.

    I wonder which one saves more keystrokes: (A) letting the default value of newly created conditional macros be false and turn them true or (B or the current algorithm) in which the newly created conditional macros are set true first and change them to false later on.

Most likely I do not understand your question. But I'd like to argue that one should first check if the argument is a number (I only check if it is an a but this could be extended) and then use ifcase for the integer cases.

Most likely I do not understand your question. But I'd like to argue that one should first check if the argument is a number (I only check if it is an a but this could be extended) and then use ifcase for the integer cases.

    I wonder which one saves more keystrokes: (A) letting the default value of newly created conditional macros be false and turn them true or (B or the current algorithm) in which the newly created conditional macros are set true first and change them to false later on.
