One way to do it would be to use the STRCOMPRESS function, which converts
multiple spaces in a string to a single space. However, this doesn't really
help in your example because you'd still have to convert the integers to
string. Thus,

msg=strcompress($
'Warning: '+string(n_sizes)+' size combinations fitted against '+$
string(n_peaks)+' peak combinations means '+ $
string(n_sizes*n_peaks)+' individual curve fits will be done.')
print,msg

isn't much better.

That's basically what I do.
