With long name element support under ISPF, when the command 'zexpand' is issued, the pop-up panel has the literal 'ENTEN255+0' appears. How is that prevented ?
ZEXPAND (expand) is an IBM ISPF command. When invoked, the IBM pop-up panel, ISPEXPND' is displayed. The panel contains the contents of the field you want to expand. The displayed information on the panel top is the name of the variable filed you are expanding along with the offset. CA Endevor has no control over this.
Use 'XE' command instead.
