The code below used to work for reading a single character, at least as

{{{
rog...@rgr> cat new-test.pir
.sub test :main
.local pmc stdin
stdin = getstdin
.local string input_string
.local int len
input_string = stdin.'read'(1)
len = length input_string
print "got len "
print len
print "\n"
.end
rog...@rgr> ./parrot new-test.pir
