FUNCTION CALENDWHEN()
Short:
------
CALENDWHEN() Uses GETDATE() function as a GET WHEN clause
Returns:
--------
<lWhen> => when condition
Syntax:
-------
CALENDWHEN([lShowonUp],[lReturn])
Description:
------------
This sets up the popup GETDATE() function for use in
a GET WHEN clause. (the pre validation block). If a date is
selected, it is assigned to the get. The Calendar function will
pop up upon entry into a GET field.
[lShowOnUp] Normally you wouldn't want this WHEN to
occur if the user is using the up arrow, and if <lShowOnUp> is
.f. (the default) it does not occur (the GET is just skipped)
[lReturn] If set to False (the default) the GET is
never actually edited, as the WHEN will always return .f., but
it is assigned the value returned by GETDATE(). By setting it to
True, the Calendar will pop up, and then the GET will also be
put through the normal get editor.
Examples:
---------
proc test
v1 := date()
v2 := date()+1
v3 := date()+1
v4 := date()+1
@10,10 get v1
@11,10 get v2 when calendwhen(.f.) // calendar pops up when the
// get is entered. No direct
// editing.
@12,10 get v3 valid calendvalid( {||v3>date()} )
@13,10 get v4

Notes:
-------
You might want to look at CALENDVALID() and
CALENDKSET() for other options.
