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
