How do I use FORMAT as I would SPRINTF?? Please Help! [message #32125]

I am quite perplexed by the IDL FORMAT keyword. I am used to MATLAB where I
can quite simply use the sprintf command. For instance, in MATLAB, the
command

s = sprintf('IDL has been driving me crazy for the last %d days', 10)

would result in a string that contains

'IDL has been driving me crazy for the last 10 days'

What I really need to do is something like this:

s = sprintf('SIZE(%s, /%s)', arrayname, somekeyword)

So if arrayname is A and somekeyword is TYPE, then the resulting string
would be

'SIZE(A, /TYPE)'

It is a meaningless example but hopefully you see what I want to do (i.e. I
need to execute IDL commands in a loop, where each time through, the command
input parameters are varying and are specified by indexing arrays that
contain the parameters)
