I am writing a program with 3 different operations. I want to create an input menu and select operations. In Wincmes I used the following code.

A) Operation 100
B) Operation 200
C) Operation 300
IP,'Enter Your Choice ',(Bask)
GO,BASK
:A
operation 100
:B
OPERATION 200
:C
OPERATION 300
Can you help me to write something similar to Dmis.

Thanks,
John
