Disk No  874
Program Title:  ZZAP version 4.0, Vector, 400 and RPN
PC-SIG version 1
 
    ZZAP is a disk editor that can read, modify, and write any sector on
the disk, as well as any file by filename upon the disk. A 4096 byte buffer
is used to hold the information to be written onto or read from the disk.
Editing can be done on a byte-by-byte basis by entering the data in HEX,
DECIMAL, OCTAL or ASCII format. You can also copy, exchange, or fill the
data of the current buffer. A window on the left half of the home screen
displays 256 bytes of the buffer at a time in all four input types. A demo
version of the next upgrade of ZZAP is included on this disk.
 
    VECTOR inspects the interrupt vector table and displays the interrupt
vectors in human readable form. VECTOR also displays some brief comments
describing each interrupt. Some interrupts are not standardized and are
difficult to interpret. The program "400" inspects the BIOS communications
area and the DOS communications area and displays these areas in human
readable form. "400" also displays some brief comments describing each byte
of the communications areas. RPN is a Reverse Polish notation calculator
based on a fully-visible stack.
