Testing for DOSKEY macro in a batch file

Hi folks;

Is there some way I can test for the existance of a DOSKEY macro within a batch file? Foe example:

if exist DOSKEY MACRO goto Menu

I know that line is no good, but wonder if there's a way.

Related to that question, is there any harm in simply redefineing a macro that already exists? For example:

:: Some batch file
@echo off
DOSKEY MacroName=function

Suppose that batch file gets run several times, the MacroName macro will get defined every time. Is this any kind of problem?

Thanks all, Dex

You could do something like this:

Code:

---

@echo off
:CheckIt
doskey/macros|find/i "dira=dir/a/o/p"
if errorlevel 0 if not errorlevel 1 goto End
:SetIt
doskey dira=dir/a/o/p
goto CheckIt
:End

---

(In other words, it'll only setup a doskey macro named DIRA if it isn't already defined).

But, this isn't really necessary. Whenever you create a doskey macro that has the same name as one already defined, it simply overwrites the old one.

Thanks Vernon, thats what I was looking for. :D
