Description

Although the ordering of these error messages is essentially arbitrary, it is important to keep the WHILE, REPEAT, and FOR errors together in a group along with the tokens that these relate to because nb_check_structure expects the token numbering and error messages to have this structure.

NB_NO_ERROR

Same as CTL_NO_ERROR and has the value zero.

NB_PROGRAM_ENDED

Internal code indicating the CoreBASIC program terminated at END or for some other reason. This is silently turned into NB_NO_ERROR when caught.

NB_OUT_OF_MEMORY

Interpreter ran out of memory.

NB_NO_SUCH_LINE

Line doesn't exist in GOTO, GOSUB, or RESTORE.

NB_SYNTAX_ERROR

Generic syntax error.

NB_BREAKPOINT

User interrupted execution or program executes STOP.

NB_WATCHDOG

Watchdog fired when debugging.

NB_IMMEDIATE_MODE_ONLY

Command is available in immediate mode only.

NB_PROGRAM_MODE_ONLY

Command is available in program mode only.

NB_ARGUMENT_ERROR

Argument to standard function is in error.

NB_TYPE_MISMATCH

Wrong type in general.

NB_UNIMPLEMENTED

I haven't got there yet.

NB_DIMENSION_ERROR

Wrong shape of array.

NB_SUBSCRIPT_ERROR

Subscript out of range.

NB_BAD_LINE_NUMBER

Line 0 is not a valid line number.

NB_STRING_TOO_LONG

String is longer than maximum length allowed.

NB_EXPRESSION_TOO_COMPLEX

Too many items on the expression stack.

NB_NEXT_WITHOUT_FOR

NEXT has no matching FOR (preflight check).

NB_WEND_WITHOUT_WHILE

WEND has no matching WHILE (preflight check).

NB_UNTIL_WITHOUT_REPEAT

UNTIL has no matching REPEAT (preflight check).

NB_ENDPROC_WITHOUT_DEFPROC

ENDPROC has no matching DEFPROC (preflight check).

NB_ENDFN_WITHOUT_DEFFN

ENDFN has no matching DEFFN (preflight check).

NB_FOR_EACH_WITHOUT_NEXT

FOR EACH has no matching NEXT (preflight check).

NB_FOR_WITHOUT_NEXT

FOR has no matching NEXT (preflight check).

NB_WHILE_WITHOUT_WEND

WHILE has no matching WEND (preflight check).

NB_REPEAT_WITHOUT_UNTIL

REPEAT has no matching UNTIL (preflight check).

NB_DEFPROC_WITHOUT_ENDPROC

DEFPROC has no matching ENDPROC (preflight check).

NB_DEFFN_WITHOUT_ENDFN

DEFFN has no matching ENDFN (preflight check).

NB_RETURN_WITHOUT_GOSUB

RETURN has no matching GOSUB (runtime check).
