Mainframe, MVS and zOS Discussion

Thanks Vadim.

Then if I try to write a JAVA program on PC which should be able to do file handling, that means it can not be executed without a mainframe?

Hello,

As it's JAVA on mainframes, is there any way I can practice writing some programs at home which will work on zOS too? :geek:

Thanks for thr quick replies.

I am learningJAVA on zOS and mightneedto work with DB2 using it also, so thanks for the link Vadim.

Hi,

I was searching this forum and could not find a book refernce for Java for zOS. What book for JAVA on zOS you recommend?

Thank you so much Anuj. This has helped greatly.
