If you are going to use the SPKA instruction, read the fine print. 'SPKA 8' will actually put you in KEY0. This is because the key has to be in the left nibble. Use 'SPKA 8*16' for KEY8. This will shift the 8 to the left 4 bits. ---------------------------------------------------------------------- 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
