For the wsave errors. Open the DT_INTS-14.bas file and at the top you'll see a section that says ...
Code:
' --- IF any of these three lines cause an error ?? ----------------------------
'       Comment them out to fix the problem ----
' -- It depends on which Chip you are using, as to which variables are needed --
wsave1      var byte    $A0     SYSTEM      ' location for W if in bank1
wsave2      var byte    $120    SYSTEM      ' location for W if in bank2
wsave3      var byte    $1A0    SYSTEM      ' location for W if in bank3
'-------------------------------------------------------------------------------
For the "Found in column 1" warnings.
You must maintain the proper indentation of the ASM blocks, as seen in the original examples.
