_IIF limits two questions

[madscijr]

Petr's example as a string I think would be...

Code: (Select All)

Dim result as String

a$ = "Yes"

result = _IIf(a$ = "YES", "a$ is YES", "a$ is not YES" )

Print result

I say think because I haven't downloaded and installed the new version yet.

Someone please correct Steve if I am wrong.

I haven't used the new _IIF command yet, but in VBA  (and VB6 if I recall?) you could use IIF to return multiple types. 

In QB64 / QB64PE, I had to make seperate functions for different return types, like below, but it would be nice if the built-in _IIF command just worked with whatever type you passed in for parameters 2 & 3 (as long as parameters 2 & 3 aren't 2 different types)... 

Code: (Select All)

'Integer
Function IIF% (Condition, IfTrue%, IfFalse%)
    If Condition Then IIF% = IfTrue% Else IIF% = IfFalse%
End Function

'String
Function IIFS$ (Condition, IfTrue$, IfFalse$)
    If Condition Then IIFS$ = IfTrue$ Else IIFS$ = IfFalse$
End Function

'Long
Function IIFL& (Condition, IfTrue&, IfFalse&)
    If Condition Then IIFL& = IfTrue& Else IIFL& = IfFalse&
End Function

'Single
Function IIFSng! (Condition, IfTrue!, IfFalse!)
    If Condition Then IIFSng! = IfTrue! Else IIFSng! = IfFalse!
End Function

'Double
Function IIFDbl# (Condition, IfTrue#, IfFalse#)
    If Condition Then IIFDbl# = IfTrue# Else IIFDbl# = IfFalse#
End Function

'Float
Function IIFF## (Condition, IfTrue##, IfFalse##)
    If Condition Then IIFF## = IfTrue## Else IIFF## = IfFalse##
End Function

'Unsigned Integer
Function IIFUI~% (Condition, IfTrue~%, IfFalse~%)
    If Condition Then IIFUI~% = IfTrue~% Else IIFSTR$ = IfFalse~%
End Function

'Etc.
