Hi,
Does anyone if its possible to use a function or variable as a parameter
or option to FORMAT ?
;e.g. if I have
print, blah, FORMAT = '(2(F6.1))'
; but I want something like this
for var = 0, 10 do $
print, blah[var,*], FORMAT = '(var(F6.1))'
Any help please will be much appreciated
Paul M.

Thanks David,
You are always available to answer the questions.
With FORMAT='(e0.1)' it's enough for me ! I didn't know this
convertion format.
Thanks !

How about this:
FUNCTION times10, number
n = String(number, FORMAT='(e0.1)')
e = StrPos(n, 'e')
IF e EQ -1 THEN RETURN, n
theNumber = StrMid(n, 0, e) + ' x 10!U4'
RETURN, theNumber
END
f = 65465.45
str = Obj_New('IDLgrText', Times10(f), /Enable_formatting)
xobjview, str
END
Cheers,
David
