The college I went to was so poor, we could only afford upper-case-only print trains for our 1403 printers. (Before that, I think they hand wrote the listings with quill pens...) They didn't have semicolons either, which made it rather difficult to debug PL/I programs. > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] > Behalf Of Bruce Black > Sent: Friday, August 04, 2006 12:26 PM > To: [email protected] > Subject: Re: [IBM-MAIN] WHY IS JCL ALLERGIC TO LOWER CASE? > > > > > > ISNT IT TRUE THAT IN THE BEGINNING THERE WAS ONLY UPPER CASE ? > Just in case you are serious: my S/360 green card (undated) > shows upper > and lower EBCDIC values.
