Size of variables in bytes? [message #9851] Tue, 02 September 1997 00:00

Hello,

is it true that there is no function in IDL 5.0.2 to get the size of a
variable in bytes (except structures)?

An integer variable seams to be 2 bytes indpendent from the system
architecture but a string seams to be 1 byte per character on a Win32
machine and 2 bytes on a SunOS-machine. I wrote a string to an
unformatted output file and looked at the filepointer to get the size in
bytes.

Is the following true and is it machine independent?

byte 1b
integer 2b
long int 4b
floating 4b
double 8b
string ???
structure n_tags(var, /length)

What's about:

complex floating
double-precision complex
pointer
object reference

Thanks for your help

Bye Chris
