I've tried res by following the help in mplab by putting the following in a
defauld 629.asm file

udata 0x20

counter1	res	1
counter2	res     1
Timer1		res	1
Timer2		res	1
w_temp		res	1
status_temp	res	1 

and all i get is this 

Error - section '.udata' can not fit the absolute section. Section '.udata'
start=0x00000020, length=0x00000006
Errors    : 1

the help example says do this

#include p16f877a.inc  ;Include standard header file
                         ;for the selected device.
group1  udata  0x20      ;group1 data stored at locations
                         ;starting at 0x20.
  group1_var1  res  1    ;group1_var1 located at 0x20.
  group1_var2  res  1    ;group1_var2 located at 0x21.
group2  udata            ;Declaration of group2 data. The
                         ;addresses for variables under
  group2_var1  res  1    ;this data section are allocated
  group2_var2  res  1    ;automatically by the linker.

which is what i did above, i even tried putting group in front of udata

So i gave up and am using cblock

Unless someone can explain what is wrong with the above :o)

We just had a long discussion about this.  Don't use EQU to define
symbols
that are intended to be variables in RAM.  Use RES instead.

In absolute mode I guess the debugger assumes all symbols could be RAM
addresses and allows you to add them to the watch window.  In
relocatable
mode there is RES specifically for the purpose of creating variables, so
the
debugger known that EQU symbols aren't the addresses of variables.
