Hiding the hex-value column

Hiding the hex-value column might be useful for users of narrow (80-column) screens. By placing the cursor on the minus sign above the "Hex Value" heading in Figure 1 and pressing Enter, the display is changed to that shown in Figure 1:

Note that the minus sign point-and-shoot field, now above the "Data Value" column, has changed to a plus sign, and that if placing the cursor on this point-and-shoot field, the display changes back to the first display with "Hex Value" visible.

The last selected "Collapse/Expand hex" option is saved in the user's ISPF profile and is used as the default display mode on subsequent Associated Storage Areas displays.
