Update Memory

You should not update memory without assistance and direction from Technical Support personnel.

If you have sufficient authority, you can update the memory displayed on the screen. To update memory:

• Tab the cursor to the data that you want to change.
• Type over the old data with the new data.

You can change either the hexadecimal or character data. The hexadecimal data is treated as four-byte fields, and the character data is treated as a 16-byte field. Therefore, if you make changes to both in the same line, the character data will overwrite the hexadecimal, since updating takes place from left to right across each row. Also, you cannot enter the period (.) as character data, since it is substituted for non-displayable characters, and consequently ignored on input. Therefore, you must enter the EBCDIC code for a period (X'4B') EBCDIC into the hexadecimal data in order to change the data to a period.

After entering the data, press the update (UPD) PF key, PF9, to make the changes effective. If you press any key other than the UPD key after you have typed changes to the data, the changes will be lost.
