That's easy, if you put the declaration and the call together:
DECLARE
INTEGER FindWindow IN Win32API
STRING, STRINGhWnd = FindWindow(
0,THIS.CAPTION)
FindWindow takes 2 parameters type STRING and their values are 0 and THIS.CAPTION, and returns an integer hWnd, the window handle
DECLARE
INTEGER SetForegroundWindow IN "User32.dll"
INTEGERnot used=SetForegroundWindow(
hWnd)
SetForegroundWindow takes 1 parameter type INTEGER, the hWnd and returns an INTEGER that in your example is not used.
