  • P asked: I was looking for availability and pricess for REXX training. I work primarily in the MVS ZOS environment. If you could send me information about this course, and any other related courses, I would greatly appreciate it.
  • M asked: Please let me know what online course cost is.
  • S asked: I like to know pricing and training method for this class(wether its online or in house training).
  • J asked: **** Please Note: My email address is wrong! It is It keeps dropping the underscore f between my first and last name ***** Please let me know how I can take the REXX Programming class on-line or by CD Rom. I work for the and need trainig in writing REXX routines. There is also one other person in my fice that needs the training. What is the cost and how do we go about getting the training? Thank you,
  • T asked: I would like to know the cost of this training, so that I can get company funding
  • B asked: I requested more information on some your REXX courses, e.g. course codes, costs, viz. REXX/TSO Programming REXX Programming I REXX Programming II OS/ REXX Programming Fundamentals OS/ TSO/E REXX Programming which I found on the following website (login required) Could you please respond!
  • S asked: How much does this training cost? I only have MB of RAM on my laptop. Can the training class still run appropriately? How soon could I take the course?
  • F asked: Rexx Programming in a mvs envirment
  • M asked: I have REXX programmer and no one to be his backup, so I'd like to get some REXX training for or other members of my staff.
