If you mean Constants, IE a named value, in VB it would be:-

Public Const cMyNumberOne = 1

Then whereever you put cMyNumberOne in the code it gets replaced with 1 when compiled. Its very useful, particularly when you have a number or string that may occasionally change during development but is used throughout a piece of code, it saves you having to search through all the code for every occurrence of it.

Anyway, DBPro does not have them as far as I have found, DarkEdit (for DB1) used to do them using a pre-compiler (and damn useful it was too), I don`t think thats made it into the new editor/compiler yet but I hope they do add it.

DBP uses the following:

#constant MyHeight 72
#constant MyAge 34
#constant MyWeight 210


N.B. Do not place any ='s after your #constant declerations or they will not compile. And also, place all of these constants at the start of your program.

Now whenever you say:

e.g. AV = (MyWeight * MyHeight) / MyAge

the compiler will automatically replace these with fixed values and not use up variable memory. Remember, these can only be used for values you don't expect to change as your program runs.

Oh!, BTW, I only found this out by accident since I too could not find any reference to this in online help or in the manual, but I knew they had to exist.

I have not seen a full list of commands missed in the manual, you can check the Keywords files in editor\keywords, which should at least give you a clue.

Incidentally there is a LOCAL too, does anyone know if this works (IE creates a variable local to a function)?

I'm not so sure, but I think creating a variable inside a function automaticaly makes it local

I know in db1 variables declared inside functions are Static. (Local and don't reset when the function is called).
