any chance to fix this?
Code: Select all
Procedure Depth()
!EXTRN _PB_Screen_Depth
!MOV eax, [_PB_Screen_Depth]
ProcedureReturn
EndProcedure
Procedure Screen()
OpenScreen(640, 480, 16, "")
EndProcedure

have you tried this?
Code: Select all
Import ""
_PB_Screen_Depth
EndImport
Import works for variables too (and TB should be able to handle it)

this code works (and is easier to port to x64 as there's no need for change [unsure if this symbol has the same name in x64]):
Code: Select all
Import ""
PB_Screen_Depth
EndImport
Procedure Depth()
ProcedureReturn PB_Screen_Depth
EndProcedure
Procedure Screen()
OpenScreen(640, 480, 16, "")
EndProcedure
Though I will take a look into the extrn issue; but if you prefer the ASM way, just comment out the !extrn line; TB can figure out that its an external symbol by itself.
