Hi All,

On a type Buf, what do I use to check for the
position of a byte pattern?


Many thanks,

Basically, what am I doing wrong here?

$ p6 'my $handle=open("filever.exe", :bin, :ro); my Buf $b; $b= $handle.read(5); say $b; say $b[2..4];; if ( $b[2..4] eq 0x90,0x00,0x04 ) {say "y";} else {say "n"}; $handle.close;'
Buf[uint8]:0x<4D 5A 90 00 03>
(144 0 3)
y


I am testing to see if the pattern 0x90 0x00 0x04 exists,
which is does not.
