JE> ! MOV CH, &H00  'CH = upper row
JE> ! MOV CL, &H00  'CL = left column
JE> ! MOV DH, &H25  'DH = lower row
JE> ! MOV DL, &H80  'DL = right column
JE> ! INT &h10
JE> locate 1,1
JE> print wow$(location%);
JE> return
  
Your values in DH and DL need to be in hex.  Also, the bios looks at
the screen as being 0-24 and 0-79.  So you would need DH=&H18 and
DL=&H4F if you wanted to scroll from line 25 and column 80.    Eric
