That's a very old version of the manual. The current one is l26ddd00.pdf, in the same directory on the server. But, I think you simply misread what was there. The console driver by default lower-cases everything _unless_ you use the % sign to indicate something should be in upper case. The example they gave in the l390dd03 document show this: input: VInput VMSG ECHO $PATH output: echo $path input: VInput vmsg echo $%PATH% output: echo $PATH This still holds true, although the l26ddd00.pdf manual words it very differently: "All lowercase characters are converted by VM to uppercase. To compensate for this, the console device driver converts all input to lowercase. "Linux and bash are case sensitive and require some specifications with uppercase characters. To allow uppercase characters to be passed to Linux, the hardware console uses an escape character *%* under VM to distinguish between uppercase and lowercase characters. Characters enclosed by two *%* are treated as uppercase." Page 251, PDF page 275. There should probably be a bug filed against the newer doc, because when I try to follow the sample on a z/VM 5.1 system, I get this back: 00: HCPPCX6531E The operating system will not accept commands from the service processor. That may very well be z/VM dependent, but I doubt it.
