-
- Peeks 'n Pokes is a collection of programs and techniques showing programmers
- how to "get underneath the covers" of IBM and compatible personal computers.
- This includes the PC, XT, AT, PS/2 and 386 machines.
-
- Included is a routine that lets you "plug" characters into the keyboard. This
- is great for running DOS commands, other programs and batch files when your
- program exits to DOS.
-
- In addition, this package includes "unprotection" for BASIC programs saved
- with the "P" option - both IBM and GW-BASIC.
-
- The manual and accompanying diskette contain instructions and sample programs
- for letting you read and change the system configuration "on the fly".
-
- While the majority of the programs are written with the BASIC programmer in
- mind, the techniques learned can be applied to any programming languauge.
- Routines are provided to the MS Pascal programmer that emulate much needed
- BASIC functions.
-
- A descriptions of the included programs appears after the following
- summary of the manual:
-
- Section 1 - Definition of Terms
- -------------------------------
-
- Defines bytes, bits, binary numbers, hexadecimal numbering, PEEK, POKE,
- DEF SEG, BSAVE, BLOAD, Port, INP, OUT, logical operators (OR, AND, XOR),
- registers, DOS and BIOS functions and Interrupts.
-
- The most important part of this section teaches you how to read and change
- the bits within a byte - the most fundamental part of computer programming.
-
- Section 2 - Getting Started
- ---------------------------
-
- How to use the programs and a listing of all programs.
-
- Section 3 - The System Configuration
- ------------------------------------
-
- Read the quipment flag. Determine the monitor, memory, number of printers,
- number of game adapters and COM ports.
-
- Read the CMOS chip on AT and later machines. Get the date and time,
- number and type of diskette and disk drives, total memory, etc.
-
- Section 4 - Unprotecting BASIC Programs
- ---------------------------------------
-
- Guaranteed to work with all versions of Microsoft and IBM interpreted BASIC.
-
- Section 5 - The Keyboard
- ------------------------
-
- Read and change the keyboard state with PEEK's and POKE's. Includes
- instructions for turning off the various shift states of the keyboard.
-
- Memory-resident program that disables Ctrl-C and Ctrl-Break.
-
- Shows you how to "plug" keystrokes into the keyboard.
-
- Section 6 - The Video Monitor
- -----------------------------
-
- Turn your monitors on and off, swap monitors, turn blinking on and off,
- read the cursor size and location, etc.
-
- Section 7 - Disks
- -----------------
-
- Read the current diskette status, how many diskettes in the system,
- number of bytes per sector, amount of free disk space, etc.
-
- Section 8 - Parallel Printer
- ----------------------------
-
- Read the number of printers, printer status, swap printers (i.e., use
- more than one printer as LPT1), etc.
-
- PEEK at the printer status BEFORE printing - avoid printer timeouts.
-
- Section 9 - Communications
- --------------------------
-
- Read the number of ports, port status, swap COM ports (i.e., use more
- than one COM port as COM1), etc.
-
- Section 10 - DOS and BIOS functions
- -----------------------------------
-
- Perform DOS and BIOS function calls from compiled or interpreted BASIC.
-
- Section 11 - Reading the disk directory
- ---------------------------------------
-
- Find filenames and extensions, file size, file date and time, attributes,
- etc. from compiled and interpreted BASIC.
-
- Section 12 - Interpretive BASIC
- -------------------------------
-
- Important PEEK locations for IBM interpreted BASIC.
-
- Section 13 - Generating Sound
- -----------------------------
-
- Shows you how to generate weird and wonderful sounds on your computer.
-
- Section 14 - Miscellaneous
- --------------------------
-
- Clicking the speaker, reading the system time to within 1/18th of a
- second. Calculate the date x days from today. Inter-program data storage
- locations.
-
- Section 15 - Finding More PEEK's and POKE's
- -------------------------------------------
-
- How to find other important memory locations, comparing two files,
- calculating the needed AND, OR and XOR arguments to isolate, clear,
- set and toggle the bits within a byte.
-
- Section 16 - MS Pascal
- ------------------------------------
-
- Pascal programs enabling DOS and BIOS function calls, emulating
- INP, OUT, PEEK and POKE.
-
