Nested Loops of Array Elements

[SciFi]

Hey, can I do this in dos?

Used to do similar on Unix but can't see how to make it work for Windows.

-----

Set Pets=(Cats Dogs Horses)

Set Cats=(FiFi FruFru Fluffy)

Set Dogs=(Lassie MrMuggles RinTinTin)

Set Horsese=(MrEd Trigger)

FOR %%A in %Pets% DO (

FOR %%B in %%A DO (

Echo “%%A %%B”

)

)

-----

Output should be…

Cats FiFi

Cats FruFru

Cats Fluffy

Dogs Lassie

Dogs MrMuggles

Dogs RinTinTin

Horses MrEd

Horses Trigger

This obviously does not work, is there any way to achieve this?

Are you talking of DOS or of a NT system (command.com vs. CMD.EXE)?

I do not have a DOS system to test this on, only a Windows 7 command prompt (cmd.exe).

This will do for the specific conditions you have listed.

Changes will need to be made if any of the pet names will have spaces.

@echo off

Set Pets=Cats Dogs Horses
Set Cats=FiFi FruFru Fluffy
Set Dogs=Lassie MrMuggies RinTinTin
Set Horses=MrEd Trigger

For %%a In (%Pets%) Do (
	For /f "Tokens=1,* delims== " %%b In ('set %%a') Do (
		For %%n In (%%c) Do (
			Echo %%a %%n
		)
	)
)

If I may, if DELAYEDEXPANSION is set, you don't even need the FOR /F:

@ECHO OFF
SETLOCAL ENABLEEXTENSIONS
SETLOCAL ENABLEDELAYEDEXPANSION

Set Pets=Cats Dogs Horses
Set Cats=FiFi FruFru Fluffy
Set Dogs=Lassie MrMuggles RinTinTin
Set Horses=MrEd Trigger


For %%A In (%Pets%) Do (
        For %%B In (!%%A!) Do (
                For %%C In (%%B) Do (
                        Echo %%A %%C
                )
        )
)

Here is a way of doing what the poster wants using VBS script.

 Dim Pets :Pets = Array("Cats","Dogs","Horses")
 Dim a,c,i,z 
'-> Loop Threw Pets Array
  For Each a In Pets 
    c = c + 1
   call SortArray(a, c)
  Next
'-> Function To Display Pets Array And Names
   Function SortArray(Item, N)
    Select Case N
     Case 1 :i = Array("FiFi", "FruFru", "Fluffy")
     Case 2 :i = Array("Lassie", "MrMuggles", "RinTinTin")
     Case 3 :i = Array("MrEd", "Trigger", "Silver")
    End Select 
    For Each z In i
      WScript.Echo Item & vbTab & z
    Next 
   End Function

Produces this output

Cats	FiFi
Cats	FruFru
Cats	Fluffy
Dogs	Lassie
Dogs	MrMuggles
Dogs	RinTinTin
Horses	MrEd
Horses	Trigger
Horses	Silver

Thanks all, I'll run that on all systems (NT, XP, W7) today and see how it goes.

Not going to have issues with spaces, naming conventions we use prohibit it.

cheers
