great... why I never tried this test... I was using zlib function from
PHP in my Rebol/Flash dialect but the Rebol compress function IS
>> print to-string zlib/decompress compress "gzip-test"
there are just 4 bytes on the end that means length of the
string (I think that may be ignored):
>> print to-string zlib/decompress head remove/part tail compress "gzip-test" -4
Rebol'sdecompress is working as well:
>> decompress zlib/compress "gzip-test"
I really don't know why RT didn't said that sooner... when I was asking
them in the feedback some time ago why there is no gzip compression
when Rebol can save PNG files, there was no reply from them:-(
never mind... now I can be independent on the PHP...
good work Jose
