- The initial band to be loaded. The default value is all.com.
- A list of directories. These directories are searched,

On unix systems the list is colon-separated, with the default
On PC systems the list is semicolon-separated with the default
- The size of constant space, in 1024-word blocks; overridden by
--constant. The default value is computed to be the correct
size for the band being loaded.
- The size of the heap, in 1024-word blocks; overridden by
--heap. The default value depends on the architecture: for
32-bit machines the default is `4096', and for 64-bit machines
the default is `16384'.
- The size of the stack, in 1024-word blocks; overridden by
--stack. The default value is `128'.
