*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! :-)

* CONST variable [, ...] = value
Assigns the value to variable.
Any later assignment to the variable causus a VARIABLE NOT DECLARED error.

OPTION BASE 1
OPEN "VIRTUAL.DAT" FOR VIRTUAL AS # 3 ' virtual data file
DIM # 3, A( 1000 ) ' array is virtual
LET A( 1000 ) = 0 ' value is written to the file
LET X = A( 1000 ) ' value is read from the file
CLOSE # 3 ' array is no longer valid
* ERROR 27, "Bad DATA"
Occurs when the READ command detects garbage in a DATA command.
* INPUT LINE
Same as LINE INPUT.
* MAT now supports lower and upper bounds.
OPTION BASE 1
MAT X( 9 ) = ZER ' lower bound is 1
MAT Y( 5 TO 9 ) = ZER ' lower bound is 5
MAT X = ZER( 9 ) ' lower bound is 1
MAT Y - ZER( 5 TO 9 ) ' lower bound is 5
* MAXLEN()
Returns the maximum string length.
* OPTION DIGITS integer
Sets the number of significant digits for PRINT.
Setting the value to zero restores the default.
* OPTION EDIT string$

Sets the STRING type suffix, commonly "$".
Setting this to "" disables STRING suffix.
Setting this to a non-punctuation character is not supported.
* OPTION RECLEN integer
Sets the default record length for RANDOM files, commonly 128.
Setting thisto zero means there is no default RANDOM record
length, so the record length must be specified in the OPEN
statement.
With OPTION RECLEN 128:
OPEN "FILE.DAT" FOR RANDOM AS #3
is considered to be the same as
OPEN "FILE.DAT" FOR RANDOM AS #3 LEN 128
With OPTION RECLEN 0:
OPEN "FILE.DAT" FOR RANDOM AS #3
causes an error.

* OPTION VERSION now requires a string instead of a literal.
Some version names have changed.
* OPTION VERSION "PDP-8"
Added LPT, PTP, PTR, TTY, TTY IN and TTY OUT commands.
Added GET() and PUT() functions.
* OPTION VERSION "CALL/360"
* OPTION VERSION "SYSTEM/360"
* OPTION VERSION "SYSTEM/370"
Added alphabet extenders. $ is a string variable.
* OPTION ZONE integer

Setting the value to zero restores the default.
* REPEAT - UNTIL added
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.
