Cursor handling and Blink


SPFLite uses the standard Windows cursor support.   To control the Blink rate (or turn it right off) go to the system's Control Panel => Keyboard settings panel.   Note that changing this setting affects the cursor blink rate for your entire system, not just SPFLite.



Vertical Cursor in Insert Mode


If checked, then a vertical bar cursor will be used when the keyboard is in Insert Mode rather than a square cursor (which can be adjusted by the next two items in this dialog).  If this option is checked, the value chosen for % Height Normal Cursor and Insert Cursor will be ignored when in Insert mode.


% Height Normal Cursor and Insert Cursor

These two values control the appearance of the screen cursor in Normal and Insert mode. The value given is a % of a full height Blob cursor (i.e. one which fills the character space). The value can range from 20 to 100%.  Note: depending on the screen font you choose, values below 20% tend to be either invisible, or fragmented dots.  So, if you have an underscore-like cursor and find that your cursor disappeared, you may need to adjust these settings.  Note the setting for the Insert cursor is ignored if you have chosen to use a Vertical cursor in insert mode (above)


Font Name, Font Pitch and Choose

These three related items allow you to choose what screen font will be used for the display. You can either directly specify a specific name and pitch (e.g. TERMINAL / 11) or select the Choose button to invoke a standard Windows Font Selection Dialog. Note that only fixed-width (non-proportional) fonts are supported.



SPFLite provides a number of fixed fonts to use, if you need something besides the system-provided fonts.  


You will notice many examples in this Help document use the RASTER font, available as an SPFLite download.  There are three Raster fonts available.  Raster is 15 points high.  Raster14 is 14 points high, and allows a few more lines on a screen.  RasterTTF is the Raster font converted to TrueType format.  RasterTTF has the same character set as Raster, but is intended primarily for printing files.  RasterTTF has the advantage of being scalable, while Raster and Raster14 are crisper fonts for the screen.  Later versions of SPFLite have added yet smaller versions of Raster, namely Raster13, Raster12 and Raster11.  Check the SPFLite download page for the most current downloadable fonts.


# Keyboard help lines to show


You can choose to have a summary of the local commands keys displayed at the bottom of the screen. You can choose from 0 to 5 lines for the display, where 0 means to omit the display altogether.  Only keys which have been defined with a Key Label will be displayed.  See "Keyboard Customization" for how to set up Key Labels.  The keys are displayed in logical key order rather than strictly by their alphabetic sorting.  


e.g.  the keys S-F1, F1, F10, A-F10, F2 and S-F2 would be displayed in order F1, S-F1, F2, S-F2, F10, A-F10.


Horizontal Cursor Ruler?

Vertical Cursor Ruler?


A hardware option on the original 3270 terminals, and some 3270 emulators, provides 'cross-hair' cursors.  These are visible full height/width lines which followed the cursor location making the position very easy to track.  It's a personal option; some users love them and other find them distracting.    SPFLite supports this style and allows you to optionally select either or both of the vertical and horizontal lines.   The lines are drawn in the MARK line color, which is set in the Screen Color section below.  A sample of cursor rulers is shown below.



Alternating Background Colors


If selected, SPFLite will use alternating bands (3 lines each) of background colors when displaying the screen.  This is similar to the use of 'green banded' paper for printouts in the past.   It assists in maintaining eye positioning when scanning text lines.   If you activate this option, the choice of the alternate color is made in the Screen Colors section below.   A sample of a screen with alternating background colors is shown below.


NOTE:  Hercules users are familiar with the Hercules Remote Print Spooler utility program HercPrt, which (among other things) has the ability to take a SYSOUT file and format it into a PDF file that looks remarkably like a computer printout on "green bar" paper - complete with sprocket holes and perforation!  This is cute and very clever, but these PDF files use a large amount of disk space.  By using alternating background colors (along with EOL AUTO and PAGE ON mode), it is possible to very closely simulate the effect of a HercPrt-formatted file without the PDF disk-space overhead.  You will still be editing or browsing ordinary text files in native mode, but the display will have the look and feel of paging through an actual hard copy printout.


If you wish to match the same colors generated by the HercPrt utility, make the main background color white, and the alternative background color a light green.  A good starting point for a HercPrt-like light green color you could try is BGR value 233, 255, 233.  You may wish to tie the profile attributes to a specific file extension like SYSOUT.



Hi-Lite Cmd line keywords?


With the large number of keywords supported by some commands, it sometimes becomes difficult to remember them all and the need to sometimes enclose them in quotes to use as literals.   This can cause some confusing error messages to appear.  If this item is selected, then recognized keywords on the command line will be displayed in high-intensity, non-keywords in lo-intensity.    For example"




The keywords 'change', 'prefix', and 'all' are hi-lighted, the remaining operands are left in lo-intensity.


Width of Line numbers (5-8)


In contrast to ISPF, which has a fixed Edit sequence number width of 6, you can make the size of this area longer to accommodate files with large numbers of lines, or shorter to allow more text data to be visible when working on displays with screen-size constraints..   You may set a value here from 5 to 8 characters.


If you change the width of this field while you have files open that are displaying "special" lines, like Profile values, MARK, MASK, BOUNDS, etc. some of these special lines "markers" may not be displayed correctly.  To correct this, issue a RESET command and redisplay the lines in question.  Typically, you will set this value to what you prefer, and then seldom if ever change it again.


Note:  Some sequence area "markers" will not fit with their normal appearance when the width is set to 5.  When this happens, SPFLite will shorten the marker to display it as best it can.  For example, =PROF> becomes PROF>.  For most markers, it will be obvious what is meant.  For NOTE and xNOTE lines, the markers had to be reformatted.  In 5-column mode, these will now appear as =##=> and =X#=> respectively.

Note:  The width of the File Manager's line command area (set in File Manager Options) and the width of the Edit screen's line command area (set in Screen Options) are different settings.  Also, the File Manager's line command area will scroll horizontally, while the Edit screen's line command area does not scroll.


Note:  A few of our more ambitious users have attempted to edit very large files, approaching and in a few cases exceeding one million lines. You are certainly welcome to try this.  However, editing files that large is what most people use databases for, not text editors - and such usage pushes the limits of what SPFLite is capable of doing.  If you intend to do that, and you are reading this section here because you want larger sequence numbers to accommodate your file, we have a few recommendations that may be of benefit:



Screen Colors - Click button to change


The bottom of this tab is used to select the colors you wish to use for the screen display. The currently selected colors are displayed in the small square box(s) to the left of each text type.  The left hand columns contains pairs of buttons.  They are related options and are in order, left to right, to match the paired text description.    e.g. Some pairs are labeled as FG / BG for Foreground(text) color and Background colors;  some as Hi / Lo for High Intensity and Low Intensity, etc.


To alter a color, click the displayed color box and you will be shown the standard system color chooser dialog.



Indicating file-modified status in the tab header


Here is an example of how these color choices would appear in the main edit window.  The current file tab shows red lettering because MODIFIED.TXT is modified, while SAVED.TXT is in blue lettering because it is unmodified.
