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')
---
> while ((c=getchar()) == ' ' || c == '\t')
153c153
< } while ((c=getc(fin)) != EOF && isalnum(c));
---
> } while ((c=getchar()) != EOF && isalnum(c));

< char *strchr();

> char *index(); /* `strchr()' in some systems */
206,207c206,207
< if (islower(c) && strchr(transtab, c))
< return strchr(transtab, c)[1];
---
> if (islower(c) && index(transtab, c))
> return index(transtab, c)[1];
