num_args()
num_args() returns the total number of the arguments passed when running the application.
Syntax
CALL num_args()
Possible values
any INTEGER
Usage and examples
num_args() returns an INTEGER equal to the number of arguments passed when running the application:
DISPLAY "Total number of arguments passed: ", num_args() AT 4, 5
will result in this display:
Together with arg_val(), num_args() is used to pass the specified parameter to the application - as in this simple program:
MAIN
DEFINE i INT
FOR i = 1 TO num_args()
DISPLAY "Argument ", i, " is ", arg_val(i) AT i + 3, 5
END FOR
CALL fgl_getkey()
END MAIN
num_args() will return the number of arguments passed when running the application no matter how you have run it - in LyciaDesktop or LyciaWeb; from LyciaStudio or from the command line - the same as arg_val().
