Because VFP don't support ( at IDE level )
an help of development of the application
( where i can add my development description, my classes and methods,
VFP and my bugs, comment ... )

Then I try to describe the method's parameters within the program.

Example;
on a class i define a myMethod, like this:

* myMethod
LPARAMETERS   ;
   parName1   ; && IN      is the name of the ....
,  parName2   ; && IN/OUT  is the partial sum, add other values ....
,  aParName3    && OUT     a array where put ....

... code

Now, when i subclassing this class,
I expected that VFP preserve the parameters layout with comments.

But this does not happen, and VFP cuts the parameters after the first comment.

Reassuming:

* This is supported partially
PARAMETERS   ;
   parName1   ;
,  parName2   ;
,  aParName3    && OUT    a array where put ....

* but it is show with a single line in subclassed method 

LPARAMETERS   parName1,parName2,aParName3 && OUT    a array where put ....

* This is not supported
PARAMETERS   ;
   parName1   ;
,  parName2   ; && IN/OUT  is the partial sum, add other values ....
,  aParName3  ; && OUT    a array where put ....

* and it is cut after the first comment

LPARAMETERS   parName1,parName2 ; && IN/OUT  is the partial sum, add other values ....

Sin!
