Mastering PowerBuilder

Before you do anything on the mail system through PowerBuilder you need to create an instance of a MailSession object.

// Instance variables
MailSession ims_MSession
MailReturnCode imRet_MailReturnCode

All the above variables are declared as instance variables since we need to refer to these variables from various events/functions in a window. In order to capture most of the mail functions return values we need to declare a variable of type MailReturnCode because, most of the mail functions return enumerated datatype values.

ims_MSession = Create MailSession

By calling the CREATE statement we are creating an instance of the MailSession object in the memory.
