1. Bc(1) has the idea that the last function letter is 'z', corresponding to decimal 26 in dc(1)'s stable[]. However, dc only gives an error for undefined functions up to LASTFUN ... _octal_ 026.
Which is correct? My bets are with bc. 2. Why is there no mention of <n> register notation for the [SsLl:;<>=] commands in dc's man page? 3. Is it wrong to love bc(1) for being a compiler? ;) Thanks, Anthony
