Request for a lisp to modify a block att referring a list.

[smallƑish]

Select the block, and check the attribute value of C_NO. Based on the C_NO value, make the following modifications to the SLNO attribute:

- If C_NO = R1, set SLNO to 1

- If C_NO = Y1, set SLNO to 2

- If C_NO = B1, set SLNO to 3

- If C_NO = R2, set SLNO to 4

- If C_NO = Y2, set SLNO to 5

- If C_NO = B2, set SLNO to 6

Error - If the C_NO att has any extra stuff apart from RYB and 1234567890, ignore the extra stuff and filter to the result

Error -  If C_NO is empty or not valid with the above. prompt C_NO value not valid

Error -  If Block doesn't have these atts prompt Block invalid

(defun c:C2S (/)
  (setq values-list '((R1 1) (Y1 2) (B1 3) (R2 4) (Y2 5) (B2 6)))
   (setq block (car (entsel "\nSelect the block: ")))
   (setpropertyvalue block "C_NO" C_NO)
  (setq SLNO (getpropertyvalue block "SLNO"))
    
  (princ "\nC_NO value not valid.")
   (princ "\nNo block selected or invalid block.")
  (princ "\nSLNO Updated Sucessfully.")  
  (princ)
)

If possible, this way I can easily modify the lisp later.

That works perfectly for this case, thank you so much for that.

can you please advice?

[smallƑish]

one more request, instead of selecting blocks, Possible to apply all the blocks present in the working file? 

if any error occur prompt function incomplete 

else Successfully completed 

[ec-cad]

Try changing this line:
((not (wcmatch (strcase val0) "R[0-9],Y[0-9],B[0-9]"))
To be:
((not (wcmatch (strcase val0) "R[0-99],Y[0-99],B[0-99]"))

Might work up to 99 ?

I have already tried that, but unfortunately no result.

[Sea-Haven]

Just a comment

R3 = 2x3+1 = 7 

R23 = 22*3+1 = 67

So no need for the mega list as can work out any RXX similar for YXX & BXX. 

Y49 = 48*3+2 =  146

B60= 60*3 = 180

hi @komondormrex 

it's modifying the c_no  att value, which is not supposed to happen.(when c_no is an invalid value.)

example R80 its replaced as R8.

[komondormrex]

make it repeat 80 in the code to having that not happened)
