repeated alphanumeric sequence as a suffix to existing attribute

[Gobel_A]

I am looking for a script that can add an alphanumeric suffix sequence to an existing attribute. I found multiple options, but most of them were just about continuous numbering in many different forms. What would I need :

1. input : specify an alphanumeric suffix (e.g. "/L" or "." or "-") [/L]
2. input : the starting number of the sequence [1]
3. input : ending sequence number [3]
4. mouse click on the attributes in the desired order will dynamically update the attribute by adding the specified sequence to the end

E.g. a series of blocks containing the attributes :
block name : attribute content

block1 : aaa
block2 : bbb
block3 : ccc
block4 : ddd
block 5 : eee

Ends after using a Lisp with the parameters set in [ ] brackets as follows :

block1 : aaa/L1
block2 : bbb/L2
block3 : ccc/L3 ;;since the ending number of the section is 3, it is reset to the starting number and continues from [1]
block4 : ddd/L1
block 5 : eee/L2

The script does not need to be complex, in fact it will only apply to a sequence of three or two numbers and will always add either "/L1" or ".1" or "-1" to 2 or 3.

Found a lisp from "gile" dated on year 2008. LISP contains more functions, but the function INCADD after a slight modification does what I need. I simply edit the code on the line 967 which resets the actual value again to 1. 

Is there a possibility to make it automacally without choosing the function  "vynUlovat" ?. Whenever the value is 4, set it again to 1 ?

Hi,

This is not LISP but the Increment plugin could help you for this and much more.

Please read the documentation (question mark button of the Increment dialog)
