You may be right; I've never had occasion to try write OO programs on the mainframe. But when I write classes in VBA, I'm not thinking primarily of sending messages between GUI objects (though you may argue that's exactly what I'm doing whether I think of it that way or not); to me it seems that the chief value of classes and class methods is a way of organizing my subroutines and functions and limiting their scope to particular uses - which seems to me would be useful in some mainframe programs I write just as well as in Excel.
I gather some OO languages are available to OMVS users here; what do the rest of you say? --- Bob Bridges, robhbrid...@gmail.com, cell 336 382-7313 /* From four miles away, the scene was mystifying, surreal.

Visual Basic. OO certainly does make sense with Windows programming (and I assume other GUI's). The idea of the GUI writers to send messages back and forth between "objects" is genius. So each bit of code (say for a button or a text box object) just sits there doing nothing until a message is sent to it. But on other platforms, forcing me to turn something into a "class" that is just a bunch of subroutines and control blocks seems like more work than it's worth. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
