I'm new to VisualAge PL/I but have used PL/I for many years on the mainframe and prefer this language over others.  I have a copy of VisualAge Professional PL/I 2.0 (vintage 1997) which I've never used until now.  I am only interested in coding PC applications without any connections to a mainframe.  

Question (1):
Can anybody tell me how I can update this version to the 2.1 variety or obtain a new version which is reasonably priced?  

Question (2):
Can IBM PL/I be used to develop actual windows apps or just apps that run under the DOS box?

Question (3):
Assuming you can write actual windows apps with IBM PL/I is there any library available to produce GUIs or is it just up to the programmer to call the native windows APIs?

Question (4):
Are VSAM capabilities inherent in the product or do you have to use some other access method outside PL/I?  If it is what DB does it actually use behind the scenes?

It appears from the website that IBM has combined all PL/I offerings into one for around $3,000 which I can't afford.  There used to be several versions available (enterprise, professional, standard, and personal).  I think the personal was only $100.  Does anybody know where you can buy still buy the standard or personal editions?
