Size of variables

The size of the various types as at 2.0b13 are:

• char eight bit signed

• unsigned char eight bit unsigned

• int eight bit signed

• unsigned int eight bit unsigned

• long sixteen bit signed

• unsigned long sixteen bit unsigned

• long long 32 bit signed

• unsigned long long 32 bit unsigned

• float 8 bit exponent, 24 bit mantissa

• pointer two byte

lcc uses 'int' as the default type for most operations including array indexing and constants. To make the code more efficient the ints were made eight bit which unfortunately limits local arrays to less than 128 elements. Note that statically allocated arrays such as image or tile data dont have this limitation.

To make it easier for porting and if/when the size of an int gets changed, it is recommended that the types BYTE, UBYTE, WORD and UWORD defined in type.h are used.
