Re: REXLANG parse buffer

Hi,

I would suggest to use

long Read(long handle, string data[], long count)

to read the data from socket directly to String variable.

Data can be parsed using  String oriented functions such as:

long strfind(str,substr); // find space occurrence
string strsub(str,idx,len); // parse number

Hope it will guide you to the right direction.

If you require any further information, let me know.

Regards, Tomas

Glad I could help.

Look for

double str2double(str)

in order to convert string to double.
