setq2

Hi All again,

It is seriously weird! I used to programming with BASIC, it was much more sensible!

Anyway, another strange thing:

(defun c:prac2 (/ a)

(setq a Y)

(prompt "\nThanks")

)

and I get:

Command: PRAC2

Thanksnil

what is "nil" for?

Please help me before I give up :wink:

Thanks in advance

Same issue as in your other post:

(defun c:prac2 ( / a)
(setq a Y)
(prompt "\nThanks")
(princ)
)

Also take care that the Y variable may not bear a value (global variable), so a will be set to nil (it is already nil since is a local variable and wasn't assigned before).

Regards,

Thanks mate I got it!

now I have another question:

I wrote:

(defun c:prac2 (/ a)

(setq a "Y")

(prompt "\nThanks")

(prompt a)

(princ)

)

and I get:

Command: PRAC2

ThanksY

How can I drop Y in the next line?

Thanks

All stings are returned on prompter, on the same line – try to switch to a new line to get it separated:

(defun c:prac2( / a)
(setq a "Y")

(prompt "\nThanks")
(prompt "\n")
(prompt a)

(princ)    
)

or

(defun c:prac2( / a)
(setq a "Y")

(prompt "\nThanks")
(prompt (strcat "\n" a))

(princ)    
)

Regards,

(defun c:prac2( / a)
(setq a "Y") 
(prompt "\nThanks[color="Red"]\n[/color]")
(prompt a)
(princ)    
)

(defun c:prac2( / a)
(setq a "Y") 
(write-line "Thanks")
(write-line a)
(princ)
  
)

Just an alternative methoid. Prin1,princ,print would probably be the more typical choice though

Thanks guys really appreciate it.
