IBM 3174 User Manual

If a left margin existedto the right of, or inthe same place as, the new right -
margin,the leftmargin is reset to the default position (first scale line position).
If you try to enter a right margin in the left margin default position, the input is
ignored. Likewise, ifyou try to enter a left margin in the right margin position, that
input is also ignored.
Note: On a 3180 Model 1 with extended function (such as scrolling), if the window
width is
less than the 80-column maximum width for Entry Assist, left and right
square brackets ([ ]) indicate the window edges.
Alternative Right Margin Type
The Greater Than symbol (>) indicates the standard right margin. When your
display is in document mode with word wrap off, the standard right margin causes
input to be inhibited when you try to enter a character at the right margin position.
The alternative right margin symbol signifies that an automatic margin release
occurs at the right margin when word wrap is off. This is useful in certain power
typing situations.
To establish an alternative right margin:
1. Position the cursor on the right margin symbol.
2. Press the Cursor Select key.
Press the Cursor Select key again to establish the standard margin symbol and
operation. The standard right margin symbol is replaced with a broken vertical
bar (I).
Setting Tab Stops
^ To settab stops:
1. Position the cursor in the desired column on the scale line.
2. Press the Forward Tab key.
The scale line is updated to show the new tab stops.
Note: Atab stop is indicated by the underscore symbol appearing in the scale
line; however, the underscore symbol is not displayed ifeither a margin or the
"end of line" signal is also set at that location.
You can set a maximum of 20 tab stops. Ifyou try to set more than 20 tabs, the
input is ignored.
