[net.sources] errors in hoc6

danoc@bonnie.UUCP (Dan O'Connell) (06/29/84)

There are a couple of small differences between the posted version
of hoc6's hoc.y  and the K&P version that makes it core dump when 
func's or proc's are read in. Edit hoc.y and replace "getchar()" with
"getc(fin)".  If you are on a USG system, replace "index(" with 
"strchr(".  With these changes the functions "fib" and "fac" (P  274)
and "ack" (P 284) in K&P work fine.

Here is the output from "diff hoc.y hoc.y.orig":

133c133
< 	while ((c=getc(fin)) == ' ' || c == '\t')
