This usage of DEFAULT

[Red2]

Question: What exactly does "DEFAULT" do/mean in the following?

// SourceFiles, convert Array to String
DEFAULT acFiles TO HB_UCHAR( 0 )

In this example what does DEFAULT do to the (array) variable acFiles?
Unfortunately I have not found any explination of this usage in the HMG help file.

Thank you for your kind help!

hi,

if you pass a Parameter it is "expect" that it have a Value else it can crash

Code: Select all

FUNCTION Dummy(a)
? a    // -> crash when have no Value

i you have a "default" Value you must not pass Parameter

Code: Select all

#include "Common,ch"

FUNCTION Dummy(a)
   DEFAULT a TO "hello world"
? a    // -> does not crash
