Is it superfluous?
« on: May 22, 2014, 11:40:57 PM »
(setq lname (strcase (cdr (assoc 2 (tblsearch "layer" lay_chname)) ) ))
In any case, can remove the strcase above (is it superfluous)? why?

hi.. If the layer name is in numeric string like "0" "123", case unchanged.
so strcase can be ignored.

( apply 'equal "hp" "happy" "hạnh phúc" "ハッピー" "幸福" "행복" ) ; error: too many arguments

I was about to post that same question

Assuming lay_chname value is the result of a user typing the layername

Code: [Select]
(if (tblsearch "layer" (setq lname (strcase lay_chname)))
        lname
  )

Depends on what's being done with the value afterwards.  If its being tested for equality against another string, then it could be important to do it or not, if case sensitivity is an issue.
If you are going to fly by the seat of your pants, expect friction burns.

try {GreatPower;}
   catch (notResponsible)
      {NextTime(PlanAhead);}
   finally
      {MasterBasics;}

Table name always  ignore case when you use search or change entities's table name or make entities with it , like you use tblsearch / entmod / entmake .
Why we used strcase , just like dgorsman said ,  Easy to use these function which no ignore case , like  wcmatch / = / member etc.  .
