Information Flow for Procedures
vWhen we call a procedure, the formal parameter temporarily
becomes another name for the actual parameter.
vIn other words, in Visual Basic the formal parameter temporarily
becomes an alias for the actual parameter, for as long as the procedure
is executing.
vAliases in real life:
o“The Sundance Kid” was an alias for Harry
Longabaugh
oTwo names; one person.
