Write an ANSI MUMPS program that conforms to the VistA Standards and Conventions. The program should ask for two values, a beginning date and ending date, and then calculate the number of days between the dates. Display the number of days. You are encouraged to make use of the File Manager or Kernel libraries for the calculation.

Here's an ANSI MUMPS program that conforms to the VistA Standards and Conventions, which asks for two values (a beginning date and ending date) and calculates the number of days between them using the Kernel library:

;This is a MUMPS program that calculates the number of days between two dates

;Ask for the beginning date
READ "Enter the beginning date (MM/DD/YYYY): ", BDATE

;Ask for the ending date
READ "Enter the ending date (MM/DD/YYYY): ", EDATE

;Convert the dates to Kernel Fileman format
SET BDATE=$$FMTE^XLFDT(BDATE,"5Z")
SET EDATE=$$FMTE^XLFDT(EDATE,"5Z")

;Calculate the number of days between the dates
SET NUMDAYS=$$FMDIFF^XLFDT(EDATE,BDATE)

;Display the number of days
WRITE !,"The number of days between ",BDATE," and ",EDATE," is ",NUMDAYS," days."
QUIT

This program uses the READ command to ask the user for the beginning and ending dates. It then uses the FMTE^XLFDT function from the Kernel library to convert the dates to the Fileman format. Finally, it uses the FMDIFF^XLFDT function to calculate the number of days between the dates and displays the result using the WRITE command.
