CALL procname ([arglist])

Transfers control to a subroutine or function.

procnameThe name of the procedure.
arglist(Optional) The comma delimited list of variables to pass to the procedure.

* Using the Call keyword is considered redundant now, which is a shame. because it does make your code more readable.
* This syntax actually comes from the days of BASIC when every line had to start with a keyword.
* When you transfer control without using "Call" you do not have to include parentheses around your arguments.
* This can be used to call functions as well as subroutines.
* When you call a function the returned value is discarded.
* For the Microsoft documentation refer to

procname arg1, arg2 
Call procname(arg1, arg2)
