Problem with DRAW or my "scanning" routine?

[TempodiBasic]

Going deeper in the issue

S4 has been declared a pixel but it is not so true
for whatching why,  run this code

Code: (Select All)

_Title "DRAW demo"
Screen _NewImage(480, 400, 256)

For a = 1 To 10
    PSet (a + 50, 50)
Next a
Draw "s4 bm51,55r10"
Draw "s3 bm51,60r10"
Draw "s2 bm51,65r10"
Draw "s1 bm51,70r10"

For a = 1 To 10
    PSet (70, a + 20)
Next a
Draw "s4bm 75,21d10"
Draw "s3bm 80,21d10"
Draw "s2bm 85,21d10"
Draw "s1bm 90,21d10"

I can affirm that
  1.  there is no issue in QB64 both QB64 and QB64pe. I would mean that the matter is so and so it must be
  2.  this is an inheritance of QB45, a bug of QB45 that lives with it and its clone. Yes to be a clone you must have also the bugs of the original program.
If you REMmed out the first two rows of code and you add on the top  SCREEN 13, you'll get the same output of QB64 from QB45.
