Parameters (Corel Paradox and Java Cross Reference Guide)

By Mike Prestwood

Corel Paradox versus Java: A side by side comparison between Corel Paradox and Java.

Language Details

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Parameters

[Other Languages]

Corel Paradox: var, const

By Reference or Value (and by constant)
The default for parameters is by value. For by reference, add var in front of the parameter. ObjectPAL also offers constant parameters where you add const in front of the parameter. A constant parameter is like a read-only parameter the compiler can optimize. You cannot assign a value to a constant parameter.

Syntax Example: 2 certification questions.

method cmCode(s String) ;...s is by value.
endMethod

method pushButton(var eventInfo Event)

  ;...eventInfo is by reference.
endMethod

method cmCode(Const s String)

  ;...s is a constant read-only parameter.
endMethod
   
proc cpNever() String
  return "Never duplicate a line of code!"
endProc
