byte loops (*solved*)

[LCD]

My experiments:

Code:

DIM x as byte

for x=-36 to 91
print x;" , ";
next x

Works well, but if startts wits -37:

Code:

DIM x as byte

for x=-37 to 91
print x;" , ";
next x

It does not work anymore, so 37 is a magic number.

Code:

DIM x as Integer

for x=-20000 to 20000
print x;" , ";
next x

did not work too.

Code:

DIM x as Integer

for x=-15000 to 15000
print x;" , ";
next x

Works well

Code:

DIM x as Long

for x=-1100000000 to 1100000000
print x;" , ";
next x

does not work

Code:

DIM x as Long

for x=-1000000000 to 1000000000
print x;" , ";
next x

Works

Code:

DIM x as byte

for x=-91 to 36
print x;" , ";
next x

Works

Code:

DIM x as byte

for x=-91 to 37
print x;" , ";
next x

DOES NOT WORK!!! hock:
OMG, how it can be?
