I'm writing a program that is simplified by having a mechanism for
"unreading" a line (or group of lines). I'm looking a various
implementations for doing that. Some use an input list that checked
for size before reading from a file. Others use more elaborate
structures.
I'm curious about possible solutions the problem and whether other
people have found a need for such mechanisms themselves.

Have you looked at the routine in Gimpel's _Algorithms in SNOBOL4_, pp. 167ff.? Mike
