Hi,

Can we receive a enhancement at Symbols/Signature/Outline to include all symbols declared into a INCLUDE item ? 
Here is a little sample where I define some symbols (equates and variables) into TEST.INC item then I include TEST.INC into my TEST program.

1/ the Outline pane do not show the TEST.INC's symbols
1.1/ I suggest you create a sub-branch into the Outline tree called like the included item then list all declared symbols 

V OUTLINE
   - TEXT.INC
   |    $ZERO
   |    ONE
   |    TWO
   - A​

2/ when I use the TEST.INC's symbols, Signature throw a 'Referenced undefined variable: ' ; which underline the symbols and fill the Problems Panel
This behavior induce a question is it a real error ? ...
If you load the INCLUDE's symbols, no Signature problems occurs ... 

with kind ragards
