I won't say its impossible but


lets take one simple usercmd

GLCDSTR 2,2,buff
macro called is

GLCDSTR?CCB macro Xin ,Yin ,Bin
MOVE?CW Xin , _X
MOVE?CW Yin ,_Y
MOVE?CB high Bin, FSR1H ;load highbyte
MOVE?CB low Bin, FSR1L ;load low byte
L?CALL tft_str_out
endm

translation to pbp2.6


X=2
Y=2
@ MOVE?CB high _buff, FSR1H ;load highbyte
@ MOVE?CB low _buff, FSR1L ;load low byte
call tft_str_out
not too difficult but its messy and could get very ugly very quickly , as henrik says an upgrade looks good
