Hello!
How can a signed 64 bits QUAD integer in PB be converted to a unsigned 64
bit integer?
Thanks!

PowerBASIC doesn't have an unsigned 64-bit data type. You can fake it using

EXT variables:
f80## = CEXT(i64&&)
...but note that due to how QUADs are implemented, and the limitations of
floating-point types, very large values lose precision. (Read the help file's
QUAD and EXT entries.) If that's not acceptable, you'll need to roll your own
data type. Google for something like "implement unsigned 64-bit integer
basic".
If you absolutely *must* have an unsigned 64-bit integer, and don't want to
roll your own, you'll need to use a different language. (For example,
FreeBASIC has ULONGINT, and QB64 (apparently) has _UNSIGNED _INTEGER64.)
