Operands


string

The string operand is required. If provides the string which, if not found, will cause the line to be marked. 

CHAR

Locates search-string regardless of what precedes or follows it.

WORD

Locates search-string when it is delimited on both sides by blanks or other non-Word characters.

PREFIX

Locates search-string at the beginning of a word.

SUFFIX

Locates search-string at the end of a word

start-column

Left column of a range (with end-column) within which the search-string value must be found. If no end-column operand, then the search-string operand must be found starting in start-col.

end-column

Right column of a range (with start-column) within which the search-string value must be found.

line-control-range

The range of lines which are to be processed by the command. The full syntax and allowable operands which make up a line control range are discussed in "Line Control Range Specification".

color-selection-criteria

A request for selection based on the highlight color of the search-string. The full syntax and allowable operands which make up a color-selection-criteria  are discussed in "Color Selection Criteria Specification".

ALL

All lines in the line range are processed. 

MX

MX requests that all lines which DO contain search-string be excluded from the display following command processing. 

MX = Make Excluded.

DX

DX requests that lines which DO contain search-string, which, if excluded, would normally be made visible, be left in their excluded status. DX = Don't change Excluded status

TOP

Normally, at the completion of the command, the first, or only, line processed is highlighted (if it is on the current screen) or the screen is scrolled to the 2nd screen line (as ISPF does) if the line is not on the current screen. If TOP is coded, then the line is always positioned as the top line of the screen, regardless of its current location.

Description


NULINE will add the User line status to all lines which do not meet the specified criteria. This is an alternative method to using the U / UU line commands to mark lines as User Lines.


When an "ordinary" V line becomes a U line , a | vertical bar will appear in the "gap column".


Example uses of the NULINE command


To mark all lines containing which do not have ABC in column 12 as User Lines:


NULINE ALL "ABC" 12


To mark all lines which do not contain the word FRED highlighted in RED as User Lines:


NULINE "FRED" WORD RED ALL
