Display Windows Message Box

Use this command to display a message using the standard Windows message dialog box.

MSG f/c/e

Required - This is the message you want to display on the screen. It can be any type of field or expression. The program will convert it automatically to a string.

WINDOWS f/c/e By setting this value to 'info', 'conformation', 'error' or 'warn' the program will display a dialog box with an information icon or with a warning icon. The information icon is the default.

NOTE: Only the first character matters, i.e., 'I' Information ,'C', Confirmation 'E' Error, or 'W' Warning.

CAPTION f/c/e

You can replace the caption of the box using this option. If you don't specify a caption the word "Information" will be displayed if this is an information message or "Warning" if it's a warning message..

EXAMPLE

The code below will display the sample dialog box.

//test UDF

#udx

#ForceRWN

define x type n

START:

x = user_func(1,3,'A')

msg 'X: '+x

quit

ret

define y,z,a type n

define do type a size 1

func user_func y,z,do

if do = 'A'

a = y+z

else_if do = 'S'

a = y-z

else_if do = 'M'

a = y*z

else_if do = 'D'

a = y/z

endif

ret a

The above is a complete program. The result, once compiled and run, would be:
