PROC name

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.
