/RL/EF/ET.AL.
/ABSTRACT----
/PIP (PERIPHERAL INTERCHANGE PROGRAM) IS A GENERAL FILE
/MANIPULATION PROGRAM FOR THE OS/8 PROGRAMMING SYSTEM.
/PIP ACCOMPLISHES DATA TRANSFERS BETWEEN ANY DEVICES IN THE OS/8
/CONFIGURATION.
/VERSION 3 MODS:
/FIXED PROBLEM WITH ONE-PAGE WRITE
/IN /S OR /Z, =OPTION IS TAKEN MODULO 100 (OCTAL)
/ WITH 100, 200, ETC. MEANING USE 0 ADDITIONAL WDS.
/DATES STILL DON'T LINE UP
/'0 FREE BLOCKS'
/ALLOW FILLING UP DEVICE TO VERY LAST BLOCK
/ALLOW 7-BIT ^C
/ALTMODE ON CD LINE RETURNS TO MONITOR WHEN DONE
/NO HALT ON /L IF NO TTY HANDLER (ACTS AS NOP)
/ /V PRINTS VERSION NUMBER FIRST TIME CALLED
/ /O AFFIRMS /Y ON ZERO SYS OR ARE YOU SURE
/=NNNN ON /I OPTION SPECIFIES LENGTH TO CLOSE FILE
/DETAILS OF PIP:
/PIP RUNS WITH THE USR (USER SERVICE ROUTINES) ALWAYS IN CORE.
/THIS ELIMINATES SWAPPING THE MONITOR. IF ANY CHANGES ARE MADE
/TO PIP, CARE SHOULD BE TAKEN IN USING PAGE ZERO LOCATIONS, AS
/THEY MUST NOT DESTROY ANY MONITOR LOCATIONS.
/CORE USED:
/FIELD 0
/00000-02777- OUTPUT BUFFER
/03000-06377- INPUT BUFFER
/06400-06577- CURRENTLY UNUSED *****
/06600-07177- INPUT HANDLER
/07200-07577- OUTPUT HANDLER
/FIELD 1
/10000-11777- OS/8 I/O MONITOR
/12000-16577- EXECUTABLE CODE
/16600-17177- HOLDS NEW DIRECTORY SEGMENT FOR /S OPTION
/17200-17577- HOLDS OLD DIRECTORY SEGMENT IN /S OPTION
/MAJOR PIECES OF CODE AND THEIR FUNCTION (BRIEFLY).
/THIS IS A LIST OF ROUTINES AS THEY APPEAR PHYSICALLY, AND
/NOT AS THEY ARE LOGICALLY CONNECTED.
/ICHAR- GENERAL CHARACTER INPUT ROUTINE. ASSIGNS NEW
/ DEVICE HANDLERS AS NEEDED.
/OOPEN- ENTERS A FILE ON A SPECIFIED DEVICE.
/OUTDMP- WRITES OUTPUT BUFFER TO OUTPUT DEVICE.
/OCLOSE- CLOSES FILE CREATED BY OOPEN
/OCHAR- CHARACTER OUTPUT ROUTINE. WRITES CHARACTERS
/ TO OUTPUT BUFFER, CALLING OUTDMP WHEN FULL.
/OTYPE- USES DEVICE NUMBER IN OUTPUT AREA OF CD TO
/ INSPECT THE DEVICE CONTROL BLOCK WORD. THIS
/ GIVES A CODE FOR THE TYPE OF DEVICE.
/SLASHG- HANDLES I/O ERRORS. IF /G IS SET, HARD I/O
/ ERRORS ARE IGNORED. IF /S AND /G ARE ON, A
/ SPECIAL RETURN IS TAKEN.
/IMAGE- IMAGE MODE PROCESSOR FOR PIP.
/SQTRA- MAIN SUBROUTINE OF IMAGE MODE, AND /S OPTION.
/PIP, PIP+1- MAIN ENTRANCES TO PIP. THE CODE ON THIS PAGE
/ INSPECTS CD OPTION WORDS AND BRANCHES TO PROPER
/ ROUTINES.
/ASCII- THE DEFAULT TRANSFER MODE IN PIP IS ASCII.
/DELETE- DELETES FILES ON OUTPUT SIDE OF CD LIST.
/DZERO- ZEROES DIRECTORY OF FIRST OUTPUT DEVICE.
/PIPERR- ERROR ROUTINR FOR PIP.
/DIRPRE- DIRECTORY PRINTING ROUTINE.
/BINARY- BINARY MODE PROCESSOR. HANDLES ABSOLUTE AND
/ RELOCATABLE BINARY FILES.
/ERPRNT- ERROR PRINTOUT.
/SQUISH- FILE COMPRESSION PROCESSOR. ELIMINATES 'HOLES'
/ IN DIRECTORY OF INPUT DEVICE.
/SYSCOP- SYSTEM COPY PROCESSOR. ALLOWS TRANSFER OF THE
/ OS/8 SYSTEM AREA.
/OPTIONS AVAILABLE IN PIP:
/A- ASCII TRANSFER; DEFAULT MODE
/B- BINARY MODE TANSFER
/C- DELETE TRAILING BLANKS. (ASCII MODE)
/D- DELETE FIRST OUTPUT FILE BEFORE PROCEEDING
/E- LIST INPUT DIRECTORY INCLUDING EMPTY FILES
/F- LIST INPUT DIRECTORY; ONLY FILE NAMES
/G- IGNORE ERRORS WHILE TRANSFERING
/I- IMAGE MODE TRANSFER
/L- LIST INPUT DIRECTORY; EXCLUDE EMPTY FILES
/O- OK TO PERFORM A SQUISH OR ZERO WITHOUT ASKING
/S- COMPRESS INPUT DEVICE ONTO OUTPUT DEVICE. ELIMINATES
/ 'HOLES' ON INPUT DEVICE.
/T- PROVIDE SIMPLE TTY FORMATTING. (ASCII ONLY)
/Y- COPY OS/8 SYSTEM AREA
/Z- ZERO OUTPUT DEVICE DIRECTORY BEFORE PROCEEDING
/=N- LEAVE N WORDS EXTRA PER DIRECTORY ENTR. VALID
/ ONLY WITH /S OR /Z.
/=N- WITH /I OPTION CLOSES OUTPUT FILE WITH THIS LENGTH
/V PRINTS VERSION # (FIRST TIME ONLY)
