I wonder if this is something that has changed and been established through
comparisons using 5.0.0.
I ask, because sometime ago there was a lot of discussion on the rexxla
list (or perhaps it was comp.lang.rexx) where after much trial and error it
was established that using charin to read the entire file into a string
followed by a makearray on the string offered the best performance.
It would be good to know authoritatively.
