Calling an user defined function

Hi,

I am trying to create an user define function to return MM DD YYYY from getCurrentTime(). Below is the program for the same.

procedure( DATE()

DATE_LIST = parseString( getCurrentTime())
MM = nthelem( 1 DATE_LIST )
DD = nthelem( 2 DATE_LIST )
YYYY = nthelem( 4 DATE_LIST )
return_list = printf("%s/%s/%s" MM DD YYYY)

)

With the above function, I want to display the date when ever the DATE() function is called. However t is being return once I call the DATE() Function. for the below code

File=outfile("readme.txt" "w")

fprintf(File "DATE : %s\n\n" DATE())

close(File)

Any Idea how the date in the above prescribed format can be returned?

Thanks,

Sanjeev

Use sprintf() to 'print' a formatted string to a variable.
You don't need to assign the sprintf() to a variable, the returned value is the string, and since it is the last statement this value is returned to the procedure.
Further you can use car, cadr etc to get list elements. It is much faster than nth() if it is called a lot of times.

procedure( DATE()
let( (DATE_LIST)
DATE_LIST = parseString( getCurrentTime())
sprintf(nil "%s/%s/%s" car(DATE_LIST) cadr(DATE_LIST) cadddr(DATE_LIST))
)
)
