adding up lisp

I have a lispoutine that adds up nummers.
When I select a text it copies and ads 1 to it.
So when I select a 2 it copies and places a 3.

(defun c:add ( / OBJECT)
(setq OBJECT (ssget))
(setq pt (cdr (assoc 10 (entget (ssname OBJECT 0)))))
(command "copy" OBJECT "" pt pt)
(command "move" OBJECT "" pt pause)
(setq cnt 0)
(repeat (sslength OBJECT)
(setq txt (cdr (assoc 1 (entget (ssname OBJECT cnt)))))
(setq txt (itoa (1+ (atoi txt)))) ; converts string into integer
(setq ent (subst (cons 1 txt) (assoc 1 (entget (ssname OBJECT cnt)))
(entget
(ssname OBJECT cnt))))
(entmod ent)
(setq cnt (1+ cnt))
)
)

This works fine.

Only I want to place a text in front of it. Like
"part 1" copies into "part 2"

"Atoi" turns a text into an integer.

How can I split the selected text (like part 1) into
"part " (=string) --> setq PART <string>
"1" (=integer) --> setq integer txt
add 1 to the integer

To combine I know you have to use:

(setq PARTTOTAL (strcat PART TXT))

But I'm stuck further.

can anybody help me?

thanks

Laura

 

Laura,
take a look at the string - handling - functions

The following table provides summary descriptions of the AutoLISP string-handling functions.

String-handling functions&nbsp;



Function



Description



(









read [string])



Returns the first list or atom obtained from a string



(









strcase string [which])



Returns a string where all alphabetic characters have been converted to uppercase or lowercase



(









strcat [string1 [string2] ...)



Returns a string that is the concatenation of multiple strings



(









strlen [string] ...)



Returns an integer that is the number of characters in a string



(









substr string start [length])



Returns a substring of a string



(









vl-prin1-to-string object)



Returns the string representation of any LISP object as if it were output by the prin1 function



(









vl-princ-to-string object)



Returns the string representation of any LISP object as if it were output by the princ function



(









vl-string-&gt;list string)



Converts a string into a list of character codes



(









vl-string-elt string position)



Returns the ASCII representation of the character at a specified position in a string



(









vl-string-left-trim character-set string)



Removes the specified characters from the beginning of a string



(









vl-string-mismatch str1 str2
[pos1 pos2 ignore-case-p])



Returns the length of the longest common prefix for two strings, starting at specified positions



(









vl-string-position char-code str [start-pos [from-end-p]])



Looks for a character with the specified ASCII code in a string



(









vl-string-right-trim character-
set string)



Removes the specified characters from the end of a string



(









vl-string-search pattern string [start-pos])



Searches for the specified pattern in a string



(









vl-string-subst new-str pattern string [start-pos])



Substitutes one string for another, within a string



(









vl-string-translate
source-set dest-set str)
