Has anybody implemented a C like printf() function?
I would like to be able to something like:

x = 1.0
y = 2.0

printf("%f + %f = %f,x,y,x+y);

Would the following work for you?

IDL> x = 1.0
IDL> y = 2.0
IDL> print, x, y, x + y, format='(f, " + ", f, " = ", f)'
1.0000000 + 2.0000000 = 3.0000000
IDL> print, x, y, x + y, format='(f4.1, " + ", f4.1, " = ", f4.1)'
1.0 + 2.0 = 3.0

Cheers,
Liam.
