Hi -Just a quick question that may not be a good one. Is there a way to divide every entry in a text file or a list by a string? In other words, I have a script that gives me a list of numbers that I want to plot, but I have to normalize by a number (that I have written to another text file), so I've been painfully doing it by hand becaue I can't find an easier way using IRAF. imarith only works on images, but I want to do the same thing basically using lists. Thanks!Josh

See the TCALC task in the TABLES.TOOLS package.If what you have is a file with some numbers and you want to divide each by a constant:[code:1:8ff4ff49cb]
list = "numbers.txt"
while (fscan (list, x) != EOF) {
print ((x / 3.14159))
}
