CONTENTS OF PROTEUS DISK H2

PAS.S        Source code for the SLAC Pascal compiler, written
             in Pascal.  Read the file PAS.DOC on Proteus disk
             H1 for background information on the compiler.
             Also see Proteus News, Vol 2, No 2 and following
             issues for more details on SLAC Pascal.  The object
             file from this program is on disk H1, along with
             all the supporting programs to compile Pascal pro-
             grams of moderate size.  Compiling PAS.S requires
             the 64K version of the SLAC system.  Disk H1 has
             the 48K version.  See INTRP.S below for information
             on creating a 64K version.

PASM.S       Source code for the post-processor (assembler) of
             the SLAC Pascal compiler.

RUN.S        Source code in 8080 assembly language for the RUN
             command that is described in PAS.DOC on disk H1.

COMPIL.S     Source code in 8080 assembly language for the
             COMPILE command described in PAS.DOC on disk H1.

INTRP.S      Source code in 8080 assembly language for the run-
             time interpreter that executes the compiled SLAC
             Pascal object programs.  This interpreter simulates
             a pseudo-computer whose "machine language" is known
             as "P-code".  Read the comments in the code to see
             how to reconfigure the interpreter to run in more
             memory space.  The more space the interpreter has
             for the P-code, the larger the programs it can run.
             To compile a program as large as the Pascal source
             code PAS.S, you must reassemble the interpreter to
             utilize all available space in a 64K Sol.  PLEASE
             NOTE:  This is still only a preliminary version of
             the interpreter.  Although the compiler will pro-
             duce P-code for floating point arithmetic (REAL
             variables), the present interpreter will not
             execute these P-codes because the floating-point
             package has not been implemented.  For the present,
             just avoid REAL variables.  In future volumes of
             the Proteus library, we expect to have an updated
             version which implements floating point operations.

INTRPn.S     where n=1,2,3,4.  These are the portions of the
             interpreter for SLAC Pascal P-code.  INTRP.S copies
             them into the input stream of the PTDOS assembler
             ASSM.  They were divided this way just for ease of
             editing with EDIT.

SORT.B       A sorting program for sorting a data file.  This
             program is written in EDBASIC and uses the Shell
             sorting method.  The READ statement will need to be
             modified to fit your file's data.  The key items
             which the sort looks at to place the record in
             order can be modified.  See the REM statements in
             the program.

SORT.F       Similar to SORT.B, but written in PTC FORTRAN.

DSORT        An EDBASIC program to create data files for SORT.B

DRAGON       DRAGON ISLAND game.  Hunt the dragon in his dark
             caves and win the hand of the princess.
