Use +\fI\-\fP to read from standard input, but \fBrenumbas\fP will refuse to +read from standard input if it\(aqs a terminal. +.sp +\fBoutput\-file\fP will be the renumbered BASIC program. If it already +exists, it will be overwritten. Use \fI\-\fP to write to standard output, +but \fBrenumbas\fP will refuse to write to standard output if it\(aqs a +terminal (since tokenized BASIC is binary data and may confuse the +terminal). +.sp +Line number references are changed in every line where they occur, so +e.g. if line 100 gets changed to 200, any other line that does a GOTO +100 (or GOSUB, RESTORE, TRAP, etc) will be updated with the new line +number. +.sp +Computed line numbers can\(aqt be updated (e.g. GOTO A or GOSUB +1000+A*100). These will draw warnings on stderr, so you can fix them +manually. +.sp +Line numbers that don\(aqt exist will not be changed (e.g. TRAP 40000). +.sp +Remember that the maximum line number for Atari BASIC is 32767. +Renumbering will fail, if the chosen start and increment values +would result in lines with numbers higher than this. +.SH OPTIONS +.sp +Options may appear in any order. The first non\-option argument is used +for \fBinput\-file\fP; the second is \fBoutput\-file\fP\&. A third non\-option +argument is an error. +.SS General Options +.INDENT 0.0 +.TP +.B \fB\-\-help\fP +Print usage message and exit. +.TP +.B \fB\-\-version\fP +Print version number and exit. +.TP +.B \fB\-v\fP +Verbose operation. When displaying a number in verbose mode, it will +be prefixed with \fI$\fP if it\(aqs in hex, or no prefix for decimal. +.UNINDENT +.SS Renumber Options +.INDENT 0.0 +.TP +.B \fB\-s\fP \fIstart\-lineno\fP +First line number in the renumbered program. Default: 10. +.TP +.B \fB\-i\fP \fIincrement\fP +Line number increment between successive lines. Default: 10. +.TP +.B \fB\-f\fP \fIfirst\-lineno\fP +Line number in original program where renumbering will start. Lines +numbered lower that this will not be renumbered. Default: 0. +.UNINDENT +.SH LIMITATIONS +.SS Computed line numbers with ON +.sp +If an ON/GOTO or ON/GOSUB uses computed line numbers (and causes a +warning), none of the line numbers after the first computed one will +be updated, even if they are constant. Example: +.INDENT 0.0 +.INDENT 3.5 +.sp +.nf +.ft C +100 ON X GOTO 10,20*Y,30 +.ft P +.fi +.UNINDENT +.UNINDENT +.sp +The 10 will be changed to whatever line 10 got renumbered to, as expected. The 20 +will \fInot\fP be changed. \fBrenumbas\fP just gives up, after the first computed +line number. +.sp +A pathological case: +.INDENT 0.0 +.INDENT 3.5 +.sp +.nf +.ft C +100 ON X GOTO 10+0,20+0 +.ft P +.fi +.UNINDENT +.UNINDENT +.sp +The 10+0 and 20+0 are considered computed line numbers, even though +the results of the computation are constant. This is because neither +Atari BASIC nor \fBrenumbas\fP does constant folding. +.sp +None of this should be a real\-world problem: computed line numbers in +ON/GOTO or ON/GOSUB are exceedingly rare. The whole \fIpoint\fP of ON is +to avoid computing line numbers. +.SS Warning line numbers +.sp +Any warning that includes a line number (such as "Computed line number") will +have the original line number, \fInot\fP the renumbered one. This is because +the warnings are generated while scanning the program to find line number +references, which happens before the actual renumbering (so the new number +isn\(aqt known yet). +.SH EXIT STATUS +.sp +0 for success, 1 for failure. +.SH COPYRIGHT +.sp +WTFPL.
