Isaac, It looks like the CI is interpreting your command as a command file name and returning syntax errors based solely on what you typed at the prompt. The range 1-26 would correspond to f.g.a, 28-36 would include lockwords, 38+ would correspond to non-MPE names. Throw in an off-by-1 error or two and 27 and 37 would be covered too... Just a guess.

It may be on other : releases, but I haven't tried them yet. : Try this: : 1) Enter an invalid command from 1-27 characters in length. You receive a : CIERROR 975 (which is correct). : 2) Enter an invalid command 28-36 characters in length. You receive both a : CIERROR 9087 and 975. : 3) Enter an invalid command 37 characters in length. You receive a CIERROR : 9086, but *NOT* a CIERROR 975. : 4) Enter an invalid command 38+ characters in length. You receive a CIERROR 975 : (again correct). : Go figure... : /isaac
