/******************************************************************************
The Klipper Library, for CA-Clipper 5.x
Copyright (c), 1994, Wallace Information Systems Engineering
FUNCTION:
_True() --> lTRUE
PARAMETERS:
None
SHORT:
Return TRUE in an inline expression (as a function call).
DESCRIPTION:
_True can be used in places where a function MUST be called, but there may
not be a function to be called.
NOTE:
I covered this in _False() (since I got to it first in the list), so see
_False() for a discussion of why this function may be useful. Hey - It could
happen!
EXAMPLE:
ValidExp = iif(type(_ValFunc) != 'U','_ValFunc()','_FALSE()')
@ 10,10 GET variable VALID (ValidExp)
In this example, the VALID is hard coded and therefore, MUST have an
expression to evaluate. VALID followed by nothing would cause a runtime
error.
