Spf; Iccf - IBM 3270 User Manual

Users of the Entry Assist function are cautioned that, when
document mode is enabled and tab stops are set, the tab key causes
space characters to replace null characters as the cursor moves to a
tab stop. This action is required to preserve formatting information
in the data stream. Tab stops should be set only in those situations
where the host program can handle the space characters that will be
generated.
4.2.1 SPF
When using the SPF edit functions, set the left margin to correspond
to the entry area. You can do this easily by positioning the cursor
where typing is to begin and pressing the Change Format key. The
scale line cursor is automatically in the same column position, and
you can immediately set the left margin at this position. The right
margin can generally be set in the rightmost column position. Thus,
the SPF line command columns will be avoided during normal entry
and edit of text material. The Backtab key or the previous word key
can be used to position the cursor rapidly to the line command field.
Entry Assist is not intended for use with the SPF text entry mode;
however, users of SPF may find it convenient to use document mode
rather than the SPF text entry mode. Document mode with word
wrap on allows "heads-down" entry of data while providing
additional entry and editing conveniences. Also, with Entry Assist's
word wrap facility, there is no need for host word adjustment; this
can provide faster host response.
If
text entry mode is to be used,
simply turn off document mode while in text entry mode; later, turn
on document mode to edit a document entered in text entry mode.
4.2.2 ICCF
When using JCCF, set the left margin at column 2. The JCCF
editor positions the cursor to this column to begin with, and, when
you press the Change Format key, the cursor appears on the scale
line in the same column. Now you may set the left margin
immediately.
Users are cautioned that, when in document mode, the Tab key
causes space characters to be entered from the current cursor
position to the next tab stop on the line. If tab stops are set and an
operator uses the Tab key to move the cursor from the JCCF
