Strictly speaking, you can't add anything to an existing string in AutoLISP; what you can do is create a modified copy of a string, for example by STRCAT, VL-STRING-TRANSLATE or VL-STRING-SUBST.

The actual problem here is probably that the ASCII 34 character is a string delimiter, so you need some tricks to make it a constituent character in a string.

You can either refer to it indirectly by calling a function: (chr 34), or just use in-string quotation by a backslash:

(strcat "23" (chr 34))

or

"23\""

Hi martti

quotation by a backslash did it well.

Thanks for reply

Marti mentioned the strcat form, (strcat "23" (chr 34))

because that is how it is usuaslly used.

Example: your dimention is in a variable, like D1, and to print it:

(strcat (rtos D1 2 3) (chr 34))

You also could use the "\"" in the strcat.
