Hi,

I am using OS/2 Warp 4 and trying to set Extended Attributes for a
file using REXX. Reviewing the online INF file the command I need is
SysPutEA().

The example given in the INF file is all well and good, but I would
like fuller explanation of what the parameters are and how they are
determined. The main concern in the example is a combination of hex
ORed with the length of the extended attribute and more.

Help or further pointers to documentation on SysPutEA() and other
functions would be appreciated.

Regards
  John

In the OS/2 programming guide you will find the complete discription of
the EA structures. There are several different types of EAs with
definitive purposes, REXX implements only one of the several types.
There are several APIs which support the quering of, getting the names
of, getting the size of, and actually retrieving the EAs, defined in the
OS/2 Control Program Ref. The REXX implementation does not show the
complexities of EAs. However, from REXX you can exploit several of the
predefind EA names as well as add your own.
