First 4 characters of Layout Tab with diesel expression

[jmcbride.161140]

Can anyone help with this? I have searched and found how to link a field to CTAB system variable. I have even found someones code to get the LAST characters of the layout tab. I need to be able to link a field to the first 4 characters and another field to any characters AFTER the first 4. An example; a layout named "3.01 Elevations" would fill one field with 3.01 and another with Elevations. Any help would be greatly appreciated!

what about using the substr command and grabbing each substring of the intial string, then passing each one to your diesel statement? I'm not very familiar with diesel, but I think it would work.

(setq str1 (substr (getvar "ctab") 0 4)
         str2 (substr (getvar "ctab") 4))

I know it way less than you, but I think it is missing $ to make it work? When I copy and paste your code into acad I get "Invalid Field Code".

Chris, you need to convert it to diesel.

I'm no Diesel person...

$(substr, $(getvar,ctab), 1, 4)

and

$(substr, $(getvar,ctab), 4)

BTW, with substr, you must start from 1. 0 will return an error.

Thanks so much!! These seemed to work perfect!

Right on! You're very welcome.

I dont know anything about diesel, my thought was get the string using lisp, then convert the result to diesel, but Alan obviously knows what he is doing.

you are right, I mis-read the help file when I was looking up the proper syntax for substr.
