Hi,
I am trying to print a list of numerical values into a .txt file to be
later imported by Excel. For this purpose, I want to change IDL's
output when printing from 2.35 to 2,35 (comma).
I was looking in the format codes in printf but was not successful...
Somebody has a clue how to do that?

You can write your own character replacing routine:
a='1.234 5.678'
b=byte(a)
p=where(b eq (byte('.'))[0], count)
if count gt 0 then b[p]=(byte(','))[0]
c=string(b)
print, c

Lajos

Thanks for the useful suggestions. I just implemented the last one.
