Hello all,
As a convention what do yo like to use for PUBLIC variables?
I use the following for LOCAL variables:
Code: Select all
cMyVar = String\Character
nMyVar = Number
lMyVar = Logical
dMyVar = Date
Thanks,
Michael

Hello Michael
As a (very old
) convention, I'm using yours for all variable, without differentiate its scopes.
With HMG, I begun prefixing control
names with its kind:
frm : Form,
txb : Text box,
chb : Check box,
lsb : List box,
btn : Button,
etc ...
Me too, time to time I need know scope of variables. So, may be useful prefixing such as : ( while "x" for type ( a, c, d, l, n ) )
xpb : public
xpr : private
xst : static
xlo : local
fe :
apb : public array,
cpr : private character,
nlo : local numeric,
dlo : local date,
etc ...
IMHO type is more important than scope, best place is beginning of.
Thanks to start this topic
Regards

Esgici,
Thanks for posting.

I feel exactly the same. I think this is overlooked all to often in naming conventions.

Is it true that all Clipper\HMG variables for arrays are PUBLIC variables?

Another type too is distinguishing a FUNCTION parameter.

For Clipper :
IMHO NO !
But arrays always passed by reference.
For HMG :
Sometimes
Me too, I don't know exactly WHEN ?

As far as I remember, all variables come to (accepted by) a function ( or a procedure of course ), are LOCAL.

Here is a nice take on HMG related naming conventions too:

Can anyone suggest a compelling reason to use single or double quotes for string values?
If not what do most Clipper\HMG programmers use?
