In "man stty" I see: iuclc Map uppercase alphabetic characters to lowercase on input. olcuc Map lowercase alphabetic characters to uppercase on output. xcase Set canonical uppercase or lowercase presentation. lcase Set xcase, iuclc, and olcuc. -lcase Disable xcase, iuclc, and olcuc. LCASE Equivalent to lcase. -LCASE Equivalent to -lcase. ... obvious concessions to upper case only terminal devices such as the KSR33. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
