* Ken UNIX:
- version bump
- windoze compile improvements
* ChipMaster: UNIX compile improvements:
- Makefile does not define LINUX anymore, whic should improve things
for our BSD cousins in the future.
- ~/{,.}profile.bas should work on all UNIXes
In all the dialects I've worked with I've never seen LINE INPUT alter
anything but EOL characters on input. The only thing it did with EOL
was stop and leave them out of the resulting string.
This is fixes that issue but it needs further scrutiny to see if it
breaks anything else and / or if a similar patch is needed somewhere
else.
I can now count the number of times a line is started with a tab!! 8-)
after make
sudo make install
addgui will put bwbasic.desktop in users Desktop
DO NOT run as sudo make addgui use
make addgui
fixed typos in Makefile
fixed typo bwbasic.sh
changed dest to /usr/local/bin
The fread()/fwrite() "stream" familiy of functions were doing unexpected
things. This could be limited to GNU libC. At any rate that is the most
common libC on the Linux platform used by most SBCs and this caused errors
while having conversations with I2C devices.
I creates a set of macros to handle the reads and writes for BINARY mode
I/O, thinking that the bare UNIX I/O may not be implemented on some
platforms. This has yet to be tested. Those other platforms would likely
not have a problem with the random seek because you can't open I/O devices
with ordinary file commands.
Macros:
- BREAD(F, V): read()s binary data from file descriptor in FILE *F into V.
- BWRITE(F, V): write()s binary data V to file descriptor in FILE *F.
- BREADS(F, V): read()s binary data from file descriptor in FILE *F into
V->Buffer.
- BWRITES(F, V): write()s binary data V-Buffer to file descriptor in FILE *F.
The BREADS/BWRITES handle writing the "Buffer" from a bwBASIC Variant. This
is used for reading and writing strings, hence the trailing S.
A test macro CMDEBUG was added to produce more diagnostic info. This will
likely go away.
This fixes an issue with colors in the COLOR command on ANSI terminals. The
first 8 color codes are in one range of numbers and the second are in a
second range. bwx_COLOR expected all 16 colors to be contiguous.
Also the code was cleaned up to use escapes where appropriate and to use
better primitive functions where available.
*WARN* we've seen this fail. See remark in renum.c.
We spent quite a lot of time fixing many things and renum now seems
able to renumber standard bwBASIC programs. bwBASIC allows for many
things that weren't available in the HP BASIC, which is where the
original renumber program came from.
If you stash line numbers in variables or calculate them you will have
to renumber those your self! :-)

REPEAT
...
EXIT REPEAT
...
UNTIL expression ' exits when expression != 0
* SPC( X ) and TAB( X )
No longer use control codes.
* UNTIL - UEND removed (to add REPEAT - UNTIL)
Here is a work-around for existin code using UNTIL-UEND:
UNITL expression -->> WHILE NOT expression
... ...
EXIT UNTIL -->> EXIT WHILE
... ...
UEND -->> WEND

Editor's Note: In the official release *ALL* of the test and sample
BASIC programs were removed and packaged in a separate "test" ZIP. I
have extracted those in to the bwbtest folder where most of the
tests were living in previous packages. I've also improved (I hope)
the EOL handling.

Patch level 2 release by Jon B. Volkoff,
11 October 1997
LIST OF PATCHES TO 2.20:
bwb_cmd.c
Fixed calling stack level logic in RETURN statement to prevent erroneous
"RETURN without GOSUB" messages.
bwb_cnd.c
bwb_stc.c
Changed continuation condition for WHILE, ELSEIF, and LOOP UNTIL
to be != FALSE, not == TRUE. More in line with common commercial
BASIC implementations.
bwb_mth.c
Fixed initialization in VAL function so that old results are not later
returned as values.
bwb_var.c
Added parenthesis level checking to dim_getparams. Using multi-level
expressions as array subscripts was causing the program to bomb.
bwx_iqc.c
bwx_tty.c
bwb_mes.h
Added second copyright notice.
bwb_dio.c
bwb_str.c
Added support for strings longer than 255 characters.
bwb_prn.c
Disabled tab expansion and print width checks when not printing to a file.
bwb_inp.c
Fixed LINE INPUT file reads to accommodate strings of length MAXSTRINGSIZE.
bwx_ncu.h
bwx_ncu.c
New files. Code for UNIX ncurses interface, compliments of L.C. Benschop,
Eindhoven, The Netherlands.
Makefile.ncu
New files. Sample makefile for ncurses implementation.
bwbasic.h
Revised defines for MININTSIZE and MAXINTSIZE from 16-bit to 32-bit limits.
Revised define for MAXSTRINGSIZE from 255 to 5000 characters.
Changed string length from unsigned char to unsigned int to support strings
longer than 255 characters.
Added support for new ncurses package.
Revised VERSION define to reflect above changes.
To implement these patches simply replace the old versions of the above source
files with the new ones and remake bwbasic.
Patch level 1 release by Jon B. Volkoff,
15 March 1996
LIST OF PATCHES TO 2.20:
bwb_cnd.c
Moved init routine for bwb_while so that it would be initialized regardless
of expression value, not just if TRUE. This was causing some segmentation
faults in WHILE-WEND loops.
bwb_elx.c
Plugged gaping memory leak. Temp variable space for expression evaluation
was being allocated but not freed when done (oops!).
bwb_fnc.c
Added check for NULL return from getenv to prevent segmentation faults.
bwbasic.h
Revised VERSION define to reflect above changes.
To implement these patches simply replace the old versions of the above source
files with the new ones and remake bwbasic.
