[M3devel] Rd.GetText Question

[Ken Durocher]

The Rd interface defines GetText as GetText(rd: T; len: CARDINAL): TEXT;

I've noticed in different values for len in different places.  Some use
Rd.Length(rd) while others use LAST(CARDINAL).

The latter would limit the text to about 2GB on a 32bit system, correct? But
does Rd.Length() always know what the length will be?

The interface for Rd states this for Rd.Length():
 "If len(rd) is unknown to the implementation of an intermittent reader,
Length(rd) returns -1."

So my question is, which should I use? Another option would be reading in
some arbitrary amount and then looping until EOF. Which method is best?

Thanks.
