Dear all
I have the following code to try and compress a string:

lcOutput = "this string is to be compressed"
llen = LEN(lcOutput)
lcBuff = SPACE(LEN(lcOutput)*1.2)
lnFinalSize = LEN( lcBuff )
DECLARE integer Compress IN d:\webserv\zlib.dll as zlibCompress ;
 string @ dest, integer @ destlen, string src, integer srcLen
Res = zlibCompress( @lcBuff, @lnFinalSize, lcOutput, lLen )

The last line fails, with the error message found in the subject. While googling a bit for the error, i saw suggestions to register the dll. I try to register, and i get the following message: "zlib.dll was loaded, but the DLLRegisterServer entry point was not found. The file cannot be registered. I don't know where did i get that version of zlib, maybe trying a newer version?
