How to keep your variables in the design?

Thank you, Dave.

How long you use this method? Wasn't problems?

Hi fxffxf

I've been trying to get this to work using the desribed method but don't seem to be able to go back to an disembodied property list.

I have the following simple example

mylist = ncons(nil)
mylist->ccw = t
mylist->middle = nil
mylist->cx = 0.12
mylist->cy = 10.192
mylist->layer = "TOP"
mylist->stype = "LEFT"

dataString = sprintf(nil " '%L" mylist)

axlCreateAttachment("_ns_planar_settings" nil 0 'string dataString)

The above does create my attachment. I can easily read it using

a_id = axlGetAttachment("_ns_planar_settings" 'string) which returns an attachment id

mylist1 = errsetstring(a_id->data) will return a list, but I cannot access the data using -> syntax

typing mylist1 at the skill development window works. but still how do I access the list?

I would expect mylist1->layer but that returns nil

Skill > mylist1
((nil stype "LEFT" layer "TOP"
    cy 10.192 cx 0.12 middle
    nil ccw t
    )
)

Best regards

Ole

 Find two differences ;)

Skill > mylist1 = errsetstring(a_id->data)
((nil middle nil ccw t))
Skill > mylist
(nil middle nil ccw t)

Yes, I too faced with this problem.
You can use: mylist1 = car(errsetstring(a_id->data))

Also, I store the data without " ' ", and add an apostrophe at the time of restoring:
sFormData = sprintf(nil "%L" _formData)
...
sFormData = attachment->data
formData = car(errsetstring(strcat("'" sFormData)))
