Just write a couple of Utility function like this:

------------------------------------------------------------------------ 
-
--
--  UtilStringPadLeft
--
------------------------------------------------------------------------ 
-
function UtilStringPadLeft theString,theStringMaxSize,thePadChar
   local myString

   put theString into myString
   repeat while the length of myString < theStringMaxSize
     put thePadChar & myString into myString
   end repeat

   return myString
end UtilStringPadLeft


------------------------------------------------------------------------ 
-
--
--  UtilStringPadRight
--
------------------------------------------------------------------------ 
-
function UtilStringPadRight theString,theStringMaxSize,thePadChar
   local myString

   put theString into myString
   repeat while the length of myString < theStringMaxSize
     put  myString & thePadChar into myString
   end repeat

   return myString
end UtilStringPadRight


Then do:

put "ImameName" & UtilStringPadLeft(mySequenceNumber,4,"0") into  
myImageName

All the Best
