Hi,
I'm a new IDL user, and I was wondering if anyone would suggest
an efficient way to make a look up table of byte arrays where the
individual bytarr's are of different lengths. Maybe ptrarr that points
to the bytarr's would be the best way. I didn't know if there was any
other way to make an indexed array of byte arrays.
Thank you.
Wendy

So long as you only want to do bytes, you can store in strings. For
example:
a = replicate("",3)
a(0) = string(byte([1,2,3,4]))
a(1) = string(byte([21,22]))
a(2) = string(byte([101,102,103,104,105,106,107]))
FOR i=0,2 DO print, byte(a(i))
the result ...
1 2 3 4
21 22
101 102 103 104 105 106 107
