If (xxx) then (xxxx) (xxxx) (xxxx)

Hi All,

how can I say this in autolisp:

(if (= a b) then do these (xxx) (xx) (xxxx)

)

I want to do several things after having a=b.

I wrote:

(if (= a b) ((xxx) (xx) (xxxx))

)

but for some reasons doesn't work!

can you please help me with this?

Cheers

Ali

got it!

(progn (xxx) (xx) (xxxx))

Progn is your new friend.

The (if (A) (B) ©) means: if A is true then do B else do C.

to do more "things" use the (progn...) command.

(if (A) (progn B1 B2 B3) (progn C1 C2...))

This structure can be translated as: If A is true then do B1, after that do B2, B3; If A is not true then do C1, c2,...

You found it out by yourself. This knowledge is more valuable.

Thanks mate,

As always explained it very nice.

Yes, I found it by searching the help. As I used to programming in Basic when I was at high-school I am familiar a little bit with programming so I was guessing something like that should be exist.

autoLISP is fantastic!!!

I am new and just started a week ago but found it incredible.

Thanks All for your support
