Does the iif() function runs faster than if .. else block?

[Clipper]

Does anyone knows if under the hood using the iif () function pointer would results in faster code compilation than the regular if ... else block and that whenever possible we should use iif () instead, not only for faster code but cleaner ? thanks.

It is NOT about the speed.

IIF() is fundamentally different than if-else.

• IIF() is a function (like MA(), EMA(), Plot()) - it does NOT change program flow. All arguments of functions are always evaluated.

• if-else on the other hand is a program control statement. It changes program flow. It allows some parts of the code to be skipped (NOT executed).

IIf function versus if statement

As mentioned by @fxshrat in ValueWhen - how to use a typical mistake users make is that they mix up if statement with IIf() function. IIf() (which stands for "immediate if") is a function, which means it takes arguments and returns the result result = IIf( condition, YesValue, NoValue ); It works with both numbers (scalars) and arrays. When any of arguments is an array it returns array. It goes bar by bar, checks condition again bar by bar and returns either corresponding array value from Yes…
