PCOUNT()

    PCOUNT() returns the number of actual parameters that have been passed
    to a procedure or user-defined function.

Syntax

    PCOUNT()

Returns

    An integer numeric value.

    PCOUNT() returns the number of parameters passed.  If no parameters are
    passed, PCOUNT() returns zero.  Note that PCOUNT() retains its value
    until you attempt to pass parameters to either a procedure or a user-
    defined function.

Usage

    PCOUNT() can prove useful when polling the DOS command line for
    parameters at the top of your program.

Example

    PARAMETERS file                  
    IF PCOUNT() = 0                  
       ACCEPT "File to use: " TO file
    ENDIF                            
    USE &file
