The third prompt is for the page width in +characters (on most terminals, this is 80; on printers, this is 132). + +The fourth option allows the user to compress the spacing between words to one +space. The text for each line will begin in the proper column at the left +margin but all other TeX spacing between words will be reduced to one space. +If the user should not select the compress option, each separate word will be +left justified in the the space provided by TeX, and sup and super scripts will +usually appear on separate lines. This option is most useful for tables and +mathematical equations. + +An example of a command line invocation with options is given by: + +vutex file_dvi over file_vut (s=2,p=4,t) + + + +Seeing TeX output! + +One of the more frustrating things about TeX and its precise positioning of +characters is that ``what you get is far more than what you can see'' on an +ordinary ASCII terminal. The only devices for TeX output on the mainframe have +been the laser printers, and that usually equates to running to get ( and +waiting for ) your output, and excessive waste of paper. Note that at most +installations, laser output is costed at about 10 times that produced by +ordinary hammer printers. + +So, a program has been written to allow the TeX user to preview the output +before sending it to the laser printer. Of course, the terminal screen (or an +ordinary printer) still cannot handle the fine spacing of TeX, nor can it +display all the characters you might wish to print. But, you will see an +approximation to the spacing of words across the line and lines down the page. + + +If your output was to a file, such as *vut in the example, you may copy that +file to an ordinary line printer, or you may use a screen editor to view it. +Note the following: + + 1. Some characters may not appear because they landed in a place already +occupied. Two characters from a small TeX font may fit into the space provided +on the screen, so vutex can only print one such character. + + 2. The output with true TeX spacing, may be wider than an ordinary screen +of 80 characters, or even a printer page of 132 characters. With ordinary text +you can compress the text and substantially reduce the width of the page, but +text with lots of off-line text will appear best in true TeX mode. A screen +editor may be used to view the output by switching from left to right side of +the page. The present installation limits the width to 160 characters per line. + + 3. Lines of small type or with extraordinary small interline spacing may +appear superimposed in spaces in the previous line. + + 4. \special has not been implemented and will be ignored by vutex. + + 5. If characters are missing from a line because of truncation or +superimposition, then a > sign will appear in the first position of that line. + + 6. Unprintable characters from ASCII fonts, such as Greek symbols, +and special math symbols, etc. will appear as # marks. However, as much as +possible, vutex will try to print a meaningful character to suggest what is in +the TeX output e.g. S is used to replace an integral sign. + + 7. A + sign in the first position of a line means that it contains super +scripts to the next line down, while a - sign means that it contains sub +scripts to the previous line up. + + 8. At the end of each TeX page, a ruler is drawn (in centimeters) to +indicate the horizontal scale (this will not appear on the TeX output to a +printer). Usually the vertical scale is only an approximation of the true TeX +spacing, and some pages may appear physically shorter than others. If it is +desired that all pages be the same length, perhaps with a form feed, this +alteration can be made to the code. + -- cgit v1.2.3
