[TriLUG] MVS mainframes

[Andrew Gray]

Does anyone have experience with MVS mainframes who might be able to 
shed some light on how they work from a users point of view?  I am still 
looking for work and was contacted about a position that entails working 
with one of these mainframes.  I have looked at the wikipedia entry and 
am unsure how much different it would be from using unix or linux.  I 
took a year of Red Hat in college and had played with FreeBSD and a 
couple distros for some time before that.  So basically I am more than 
comfortable with linux and run it full time and am wondering how 
difficult it would be to pick up and how different it would be.

-Thanks for any help
