I REALLY REALLY wish (Aside from object oriented programming model with classes) the ability to be able to DISABLE dynamic declared variables so simple spelling mistakes dont take so much time to find.

For Example: REQUIRE VARIABLE DECLARATION Flag (Default False)

This way any var you use needs to be declared or the compiler would complain that the variable doesn't exist if its not declared as a DIM or GLOBAL or "A as SomeType" or something.

If the language does this now - I could not find the keyword - Can ya help?

Thanx
Jason

No the language doesn't do it now, but it is an excellent suggestion for a compiler improvement.

alot of people have been clamouring for Option Explicit for a while now, maybe it will be included in one of the new IDE's coming down the pipe

Possibly, but it would be *much* easier for Lee to add it at compiler level, and more reliable, than if an IDE added it at its level. This kind of check is the responsibility of the compiler, not the IDE.

The language may change in a future update, which would break an IDE implementation of Option Explicit.

I suggested something like this ages ago - I might have e-mailed it to Lee to...

It sounds like a great idea.

If user input is needed to get its implementation under way then consider this my vote!

Yep, it's trivial for LEE to add. Hence, Play Basic already supports it.

I'd certainly like to see a better MID$ command, rather like...

MID$(string,start,length)

eg

a$="The quick brown fox jumps over the lazy dog"

print mid$(a$,20,5)

Prints "jumps"

A full MID$() already exists as a part of my utility plug-in.

I'd really REALLY like to see OPTION EXPLICIT or equivalent.

@JSN

Mid$ already has this functionality, it just isn't documented.

Are you serious??? You mean the Mid$ isn't string, start, length? That command is as old as basic itself - but it works different in DBPro.... Caveats.

Well...

I've just tried using this and I'm getting an error.

IF it's not documented, then does anyone have an example to show...?

OPTION EXPLICIT: I Believe this would make coding heaps faster - especially at 3am on 15th Cup of coffee with the hands shakin from all the CaFfEiNe!

What about it Lee?

It's not documented because it doesn't exist, unless you have a plug-in that provides it.

@IanM

Yeah, I appreciate what you're saying, and I believe the way to get this is via your plug in.

However...

Does this mean the functionality IS available, but not documented, if so, what are the correct specs.

No, believe me. I *absolutely* know that this command doesn't exist as a 3 parameter version

Every command (and I do mean every command) is automatically captured by my interface library build system. I can even provide a list of the functions that don't have commands attached to them.

MID$ only appears once in the whole of the DBPro libraries.

I guess I'll have to write a little codesnip? I have an excellent FreePAscal Lib - I wonder If I should make some dll - even works with MySql Database - good way to store lots of media and data for 3D stuff hehe.

I am sorta dealing with lack of option explicit by making type called "rtFileNameGlobals" and then I make a global instance of it with minimal chars as I'll be typing it alot:

global grF as rtFilenameGlobals

` rt = record type, gr=global record

and then I access my vars like this: grf.iMyInteger = 10

This helps considerably - as it allows organization (when debugging
it helps me find what source file manges that by the global record variable name.

I too would like this feature, but only as an option that I can dissable within the editor, why?

This is the sort of thing that helps debugging, and when I am debugging I like to have onscreen what I have chosen to be onscreen - not the start of my code that gives an explicit command.

Declared variables, whatever their proper name, is a concept I am used too from other platforms and one I would appreciate (albiet out of the habbit of using).

I think by default such an option should be off, because it is not ... and here's the killer that may negate it's inclusion, it is not BASIC.

Neither are multiword commands...Basic Syntax I mean

Camera Position X() <- Multi Keyword Function? Syntax? Basic?

I agree it should be an optional thing - There is nothing more frustrating than debugging an issue just to find its a mispeling

Well, I for one would wholeheartedly cheer if there was an OPTION EXPLICIT or equivalent in DBP.

But that's never stopped any implementers of Basic. Basic is the least standardized language of all the great computer languages, and every Basic package is incompatible with everything else.

So, I wouldn't lift an eyebrow if DB was pushed further away from any sort of "standard" basic. There isn't any such thing anyway.
