    I have what seems like it should be a simple problem, when I use the string() function in this line: STRING(j + 1,'.bmp') where j is an integer, i get spaces before the filename created, so that it is in a form: ****1.bmp, where the * is a space. is there a quick way to get rid of these spaces or do I have to convert j from an integer to a character and use the character in the function?

    Although there are several IDL language options, I think the most traditional solution for this problem you pose, is to wrap all integers and integer-type variables in IDL's STRTRIM function. For example: myfilename = strtrim(j + 1, 2) + '.bmp' The '2' argument at the end means strip off BOTH leading blank's and trailing blank's. STRTRIM is needed because IDL has very specific default formats for number-to-string conversions, default formats that include leading blank spaces. James Jones
