Heather,
You can do string concatenation and conversion

print, "this is a number " + string(numbers[6])

you can also have more control... remove the blanks:

print, "this is a number " + strtrim(numbers[6],2)

or even add formats:
print, "this is a number " + string(numbers[6],format = '(I)')

and with no blanks

print, "this is a number " + strtrim(string(numbers[6],format = '(I)'),2)

Jean
PS: replace print, by text = if you want to save the string
