The semicolon is needed and so is the GOTO. Richard Jackson Richard Jackson and Associates Ltd.

The forum is sponsored by IBM, and includes -|the participation of both Barbara, and Hans. -| -|As most of you are aware, the biggest enhancement to the new -|release is the -|free-format "CF-spec" that has been discussed at length on this list. Here -|is an example, straight from an article written by George Farr, of how we -|would code the new free-format statements: -| -| -|/free -| -| Read(n) MASTER; -| If (not %EOF); -| /copy something -| For i = 0 to num; -| x = y(i); -| EndFor; -| EndIf; -| -| /endfree; -| -|I'd like you to take notice of the semi-colon at the end of each -|statement. -|According to the new rules, each program statement MUST terminate with a -|semi-colon - ala C/Java. -| -|The only reason that Java required this at all is because it was -|designed to -|closely resemble C syntax, in order to facilitate adoption of the language -|by existing C programmers. Why C had it in the first place is -|beyond me. But -|now we're being shackled with the same superfluous baggage. -| -|There is no shortage of free-format languages that have managed to do the -|job without requiring the programmer to type an explicit end of statement -|character. Why does RPG need one? Think about this folks. EVERY -|SINGLE LINE -|of code needs the new terminator. How many extra keystrokes will -|that amount -|to in a given day of coding? And what is it gaining you? NOTHING! -| -|One other point that should be brought to your attention is the -|elimination -|of the GOTO statement from the free-format specifications. How many of you -|have code that looks like this: -| -|P DataOk B -| PI N -| -| * Clear error conditions -|C Clear GlobalErrStruct -| -| * Perform an edit -|C If Not SomeCondition -|C Eval MsgID = 'ERR1000' -|C Eval MsgData = 'MyDiagData' -|C Eval CursorOnField1= *On -|C Goto Proc_Error -|C Endif -| -|* Perform a bunch of other edits -| -| * Clean up & Exit -|C Return *On -| -| * Errors found -|C Proc_Error Tag -|C Eval GenErrorID = *On -|C CallP SndDiagMsg( MsgID: MsgData: -|'*CALLER') -|C Return *Off -| -|P DataOk E -| -| -|Granted, it's not the only way to accomplish the goal, but (IMO) -|it is clean -|and simple. You may choose to do it using nested IF's, or one big -|SELECT, or -|a handful of other ways. But the point is that you have a choice. Now, IBM -|has decided to take away one of our choices in the matter. -| -|If any of you have an opinion with respect to either of these -|limitations, I -|urge you to speak up now. Once released, the chances of us getting this -|changed will be slim for the GOTO, and absolutely NONE for the statement -|terminator. -| -|Ideally, you can participate in the feedback forum at www.as400network.com -|to share your opinions. If you can't do that, then please share -|them on this -|list; since we know that Hans & Barbara monitor it. -| -| -|Regards, -| -|John Taylor -|Canada -| -|+--- -|| This is the RPG/400 Mailing List! -|| To submit a new message, send your mail to RPG400-L@midrange.com. -|| To subscribe to this list send email to RPG400-L-SUB@midrange.com. -|| To unsubscribe from this list send email to RPG400-L-UNSUB@midrange.com. -|| Questions should be directed to the list owner/operator: -|david@midrange.com -|+--- +--- | This is the RPG/400 Mailing List! | To submit a new message, send your mail to RPG400-L@midrange.com. | To subscribe to this list send email to RPG400-L-SUB@midrange.com. | To unsubscribe from this list send email to RPG400-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +--- +--- | This is the RPG/400 Mailing List! | To submit a new message, send your mail to RPG400-L@midrange.com. | To subscribe to this list send email to RPG400-L-SUB@midrange.com. | To unsubscribe from this list send email to RPG400-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
