Any later assignment to the variable causus a VARIABLE NOT DECLARED error. * DIM now supports lower and upper bounds. OPTION BASE 1 DIM X( 9 ) ' lower bound is 1 DIM Y( 5 TO 9 ) ' lower bound is 5 * DIM now supports virtual variables. 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LET A( 1000 ) = 0 ' value is written to the file LET X = A( 1000 ) ' value is read from the file CLOSE # 3 ' array is no longer valid * ERROR 27, "Bad DATA" Occurs when the READ command detects garbage in a DATA command.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 program name used by the EDIT command. Setting this to "" disables EDIT command. * OPTION FILES string$ Sets the program name used by the FILES command.

Setting this to a non-punctuation character is not supported. * OPTION PUNCT PRINT char$ Sets the shortcut PRINT character, commonly "?". Setting this to "" disables the shortcut PRINT character. Setting this to a non-punctuation character is not supported. * OPTION PUNCT QUOTE char$ Sets the QUOTE character, 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 RENUM string$ Sets the program name used by the RENUM command. Setting this to "" disables RENUM command. * OPTION SCALE integer Sets the number of digits to round after the decimal point for PRINT.

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 * from Howard Wulf, AF5NE 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. - ChipMaster
