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 Sample Associated Storage Areas display and pressing Enter, the display is changed to that shown in Sample Associated Storage Areas display with hex value column collapsed:

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.
