Task

Load the entire contents of some text file as a single string variable.

If applicable, discuss: encoding selection, the possibility of memory-mapping.

Of course, in practice one should avoid reading an entire file at once
if the file is large and the task can be accomplished incrementally instead
(in which case check File IO);
this is for those cases where having the entire file is actually what is wanted.




      input(.inbin,21,"filename.txt [-r524288]")     :f(end)
rdlp  buf = inbin                                    :s(rdlp)
*
*  now process the 'buf' containing the file
*
end
