Re: ACCESS to IFS

The parameters for the IFS read API returns the Data which must be defined at a
max length.  Defining this max length makes RPG init this when the program is
loaded. If you define the parm at 32000 for a read, then the program must init
this field when it is loaded.  Is there a way of getting the information without
reading the data, just getting the pointer?

Moving the pointers is faster than moving the data.

If I define the field at say 512. Then it should return the correct pointer
location for the data, but I do not think all the data will be guaranteed to be
there.

I am using the API's but isn't moving the data and clearing the space taking
longer than passing the pointer?
