For example, all labels within a routine can have the same name as the routine, plus some extension - e.g. in routine AddNumber, the first label would be AddNumber_1, the second AddNumber_2 etc.
If you do that do never ask me to look at your code.

If you want to link your labels to the routine where they are used preface with an abbreviation like this
AddNumber:
mov a,ANOindex;
mov r0,ANOcounr;
etc

That way you can link to routine and still have meaningful names.
