I have two functions:
Function1
{
Function2
return 1
}
Function2
{
return 0
}
After executing Function1
it should return 1
, but it returns 0
. Why is that?

PowerShell "return values" don't really work the way you'd be used to from other languages. The important thing to remember is that all output is captured and returned. The return
statement is basically just a logical exit point.
For example:
Function Return-Zero {
return 0
}
Function Return-One {
Return-Zero
return 1
}
Return-One
Since the return value of Return-Zero
was not stored in a variable, it is part of the output. Running the above will have the output:
0
1
...which is probably what you're getting. If you store the return of Return-Zero
in a variable, it is not part of the output.
Function Return-Zero {
return 0
}
Function Return-One {
$var = Return-Zero
return $var
}
Return-One
Output of the above is 0
.
