fwh functions

[D.Fernandez]

Friends, where can I found FWH functions.
Something like this: HB_BASE64DECODE( <cBase64> ) --> cString | Decodes a base 64 encoded character string.

Thank you very much
Regrads.

HB_BASE64DECODE() is not a FWH function, it is a xHarbour function. So you can find it and many others in the xHarbour documentation. There is a very good one sold by xharbour.com guys:

Enrico, thaknyou, very much.

I was asking for a .txt file whith all FWH and Harbour functions to make a json file to MSCode.

Thank.
Regards

Ruben,

Here it is all FWH functions info:

I have theese routines written by Badara (an old fivewin user).
I hope they fulfil your needs.
