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.




      file% = OPENIN("input.txt")
      strvar$ = ""
      WHILE NOT EOF#file%
        strvar$ += CHR$(BGET#file%)
      ENDWHILE
      CLOSE #file%
