How set the value of the attributes

[LingoSag]

First,excuse my english, my native language is french

I try to set a SYMBOL with !define inside a macro.

The final target is: set the value of attribute at compile-time.

I take Caption for this exemple.

Later, if it work, I use ${If} ${Else}... for decide which value for each attributes...

I don't understand why is so difficult to set the value of this attributes

at compile-time for differents circumstances ???

-inside section...........No permit

-inside function..........No permit

-With variable............No permit

How set the value of this attributes in a flexible way ?
