strcat help sought

Lisp question

(setq ope(getreal "\nenter the actual ope size..."))

(setq wname (strcat ope "w"))

(command "-insert" wname p2 "" "" p3 "") ; inserts a standard block.

What I basically want to do is create a new variable that will be whatever number I enter for the variable

Barking up right tree just got to keep from mixing fruits and nuts.

'ope' is a real number. 'Strcat' works on only strings. So using'ope' in 'strcat' function you need to convert it to a string using 'rtos'.

If 'ope' can only be an interger you should use 'getint' rather than 'getreal'. Convert an integer to string using 'itoa'.

Yes. Strcat can deal only in strings, so you shoulkd convert the real / int in to string by using

for Int - Itoa (integer to ascii)

or for real it is RTOS - real to string

eg;

(setq ope (getreal "sdjsd")
       combine_Ope (strcat (rtos ope) "W")
)

thanks guys.

slowly but surely i'm getting the hang of lisp. my routines are getting more elobrate each time, i'm still a looooong way of yet, but i'm getting there.

Ta.

Diarmuid

i would like to ask how the RTOS part can make an integer a whole number.

(if (null NUMBER) (setq NUMBER 6))
(setq NUMBER(getint (strcat "\nHow many ?<" (rtos NUMBER) ">: ")))

The output would be "How many? :"

But i would want it to be "How many? :".

Any indication on how the '.000' part can be removed?

p.s. This is just a learing case for me, i know (or at least in my code at the moment) the number 6 would not be saved if i just press enter after the question)

Use itoa instead. Or (rtos number 2 0).

To quote the lisp bible (Autocad release 12 paper copy)

(rtos number [mode [precision]])

mode

1 Scientific

2 Decimal

3 Engineeering Feet & dec inches

4 Architectural Feet & inches

5 Fractional

Thanks guys!
