===== PROC ✓ =====

===== SYNTAX =====
     PROC name

==== PURPOSE ====

This keyword has multiple meaning. If the identifier that follows this
command is not already defined, this can be used to give a label (name)
to a pat of the program. This makes subprograms independent of their 
position in the program and makes it easier for the programmer to keep 
track of things (names are easier to assign to a purpose than line numbers).
The ''PROC'' command is used to define the name of such a subprogram 
(or jump target). The name may consist of several words separated by spaces. 
A leading space is not significant. Other BASIC commands may be in the same
line as ''PROC''.

If, instead, the identifier has been already used for a procedure, then this
command will call the procedure, as the instruction ''CALL''.



==== EXAMPLE ====
    PROC factorial
