After the ID is a list of offsets for the pages of normal PCX. The list is a simple array of = 4-byte integers, the last of which has a value of 0 to mark the end of the array. The first page is page 0, and the offset from the beginning of the file of the nth page is stored at array location n. = The array has a maximum of 1024 entries, with page numbers ranging from = 0 to 1023, and thus giving a maximum size of the header to 5000 = (1024x4+4) bytes.
