Table 9-1 Notes
1. The lower bound of an HP Pascal array can be any integer, but the
lower bound of a C array must be zero.
2. HP Pascal allocates one byte for a Boolean variable. It stores
the value in the rightmost bit.
3. A C enumerated variable corresponds to an HP Pascal integer , but
an HP Pascal enumerated variable corresponds to a C unsigned char
if it is one byte, a C unsigned short if it is two bytes, and a C
unsigned int if it is four bytes.
4. A C union type corresponds to the variant part of an HP Pascal
record type. For example:
The C type union
typedef union
{
int In ;
