A freind of mine wrote  a nice thing for just this application.  It's a
function called
padnumstring.pro

here it is


copy all below this line
---------------------------


; Pad 0's at the beginning of a string to make it a
; certain number of characters.
;
; Meant only for integers !
;

function padnumstring, number, length

numstring = strcompress(string(number),/r)

if strlen(numstring) gt length then begin
 print,'number is too big !'
 stop
 end

repeat begin
 if strlen(numstring) lt length then numstring='0'+numstring
 endrep until strlen(numstring) eq length

return, numstring

end

----------------------------
to above this line

just copy this and name it what I called it.

to make it work put it in a place where you can read idl files
usage:

to get a string from a two digit integer with 5 digits padded with zeros

idl> num = 10
idl> a = padnumstring(num,5)
idl> print,a
    a = 00010
