Assigning Values to Structs
Structs are assigned to Structs either by reference or by value.
Structs are assigned by reference when the target
(to the left of the = sign) is a variable or parameter.
Structs are assigned by value when the target is a Struct member.
Assignment by Reference
The following code assigns the Struct referenced
by struct component variable vInputStruct to a local variable
vBook:
variables any vBook endvariables ; $vInputStruct$ is a struct component variable that refers to an existing Struct vBook = $vInputStruct$
Now, both vBook and
$vInputStruct$ refer to the same Struct. The Struct itself is not affected.
Assignment by Value
The following code assigns a value to the
title member of the Struct referenced by vStruct:
vStruct->title = "Installation Guide"
The following code assigns the Struct referenced
by vChapter to a Struct member named preface.
vStructMember->preface = vChapter
In this case, the contents of
vChapter replace the preface member.
