I was readking that a "CALL" subroutine statement transfers control to the subroutine.

My question is: does that mean the VBA code will wait for that subroutine to complete before continuing on with its code?

{Example:)
main code
Call RTN_A
code
code
exit

RTN_A
code

In some code I wrote which works OK, I added a 5 second wait in the main code to allow the subroutine code to complete.
Application.Wait(Now + TimeValue("00:00:05")

Is this unnecessary?
Or if the call statement says, run this subroutine and continues on without waiting for it to complete, then I need the WAIT statement in my case.

The code is Excel VBA calling a user-created sub procedure, which by definition, is not returning a value.

Since Excel VBA is not expecting or waiting for a value from a user created sub procedure, does the code wait for the sub procedure to complete before continuing on in the code?
