Editor-assigned labels

The editor automatically assigns special labels that begin with the letter Z. Only the editor can assign a special label.

These built-in labels are:

.ZCSR: The data line on which the cursor is currently positioned.
.ZFIRST: The first data line (same as relative line number 1). Can be abbreviated .ZF.
.ZLAST: The last data line. Can be abbreviated .ZL.

Unlike other labels, .ZCSR, .ZFIRST, and .ZLAST do not stay with the same line. Label .ZCSR stays with the cursor, and labels .ZFIRST and .ZLAST remain with the current first and last lines.

Note: Labels that are five characters long and begin with the letter 'O' have special meaning to the HILITE feature of the ISPF editor. When a 5-character label starting with O, such as .OAAAA, is shown on the screen, the language highlighting features are disabled and the lines with these special labels are displayed in blue. This feature is used by the COMPARE command.
