i made a brain-o and typed 'limit datasize maxproc 256' instead of
'limit maxproc 256'.

>Description:

limtail() strips off the leading 'm' when its second argument is "megabytes".

>How-To-Repeat:

% limit
cputime         unlimited
filesize        unlimited
datasize        65536 kbytes
stacksize       8192 kbytes
coredumpsize    unlimited
memoryuse       14572 kbytes
memorylocked    4858 kbytes
maxproc         40 
openfiles       64 
% limit datasize maxprox 256
Bad scaling; did you mean "egabytes"?.
% 

% gdb -q ./csh
(gdb) b limtail
Breakpoint 1 at 0x10293: file func.c, line 1276.
(gdb) r
Starting program: /tmp/csh/./csh 
% limit datasize mblah

Breakpoint 1, limtail (cp=0x2d380, str=0xfd5f "megabytes") at func.c:1276
1276        while (*cp && *cp == *str)
(gdb) print *cp
$1 = 109
(gdb) print str

1273        Char   *cp;
1274        char   *str;
1275    {
1276        while (*cp && *cp == *str)
1277            cp++, str++;
1278        if (*cp)
1279            stderror(ERR_BADSCALE, str);
1280    }
(gdb) step
1277            cp++, str++;
(gdb) step
1278        if (*cp)
(gdb) print str
$3 = 0xfd60 "egabytes"
(gdb) quit
The program is running.  Quit anyway (and kill it)? (y or n) y

>Fix:
	
i don't know.  use rc instead of csh? :)
