Does anyone out there know why the unsigned integer type has
never been implemented in IDL? Has anyone written a small
package of routines to deal with them painlessly? I've always
handled on a case-by-case basis by reading the signed shorts into IDL
and then converting them to LONG, using the MSB of the short to
turn the sign bit into the appropriate power of two. Don't all C
compilers have unsigned shorts as a standard type? Is there anyone
else out there who would like to see unsigned integers elevated to
a legal type?
