Wrong Compiler Warning (minor problem)

[Raul Almeida]

I'd like to report a minor compiler warning problem.

When I compile a code like the one below compiler gives this warning: Warning W0004  Codeblock parameter 'E' declared but not used in function '*****************'

"

...

LOCAL aIndexes := {}

aEval( aDbs, { |e| aAdd( aIndexes, e->( ordkey() ) ) } )

...

"

It doesn't consider the alias pushing as a variable use.

warning ok, is not the alias.

change:
{ |e| aadd(...) }

to:
{ || aadd(...) }

JoséQuintas, please look carefully to the code.. the variable e is used and needed!

...

LOCAL aIndexes := {}

aEval( aDbs, { |e| aAdd( aIndexes, e->( ordkey() ) ) } )

...

The e word is not a variable. It is an alias.

Raul,
The warning is correct.  In the code block as you have it, e is a literal work area. To make it work correctly, you need parenthesis around e to use the value that is stored in e as the alias:

LOCAL aIndexes := {}

aEval( aDbs, { |e| aAdd( aIndexes, (e)->( ordkey() ) ) } )

Ohh.. that's true.

Thanks a lot man. Sorry for the false alarm.
