If Statement (Corel Paradox and C++ Cross Reference Guide)

By Mike Prestwood

Corel Paradox versus C++: A side by side comparison between Corel Paradox and C++.

Statements

Common statements such as if statements, loops, etc.

If Statement

[Other Languages]

Corel Paradox: If..Else..EndIf, or switch

ObjectPAL supports a simple If...Else...EndIf statement.

Notice ObjectPAL does not support an ElseIf feature as part of an if statement. Instead use a switch statement

Syntax Example: 1 certification question.

'Does ObjectPAL evaluate the math correctly? No!

If (.1 + .1 + .1) = .3 Then
  msgInfo("", "Correct")
Else
  msgInfo("", "Not correct")
EndIf

'Switch statement example.
switch
  case x = "Nate": MsgInfo("", "Hi Nate")
  case x = "Felicia": MsgInfo("", "Hi Felly")

  otherwise: MsgInfo("", "Who are you?")

endSwitch

C++: if..else if..else

Same as standard C.

Syntax Example:

//C++Builder example using the VCL ShowMessage.

int x;

x = 8;

if (x == 10) {
  ShowMessage("x is 10.");
} else if (x < 10) {
  ShowMessage("x is less than 10.");
} else {
  ShowMessage("x must be greater than 10.");
}
