      HOW TO FIT VERY LARGE TEXT FILES INTO TI WRITER

          Text files ported over from other types of computers and
     converted into DV80 format for use with the TI are sometimes enormous,
     occupying several hundred sectors.  Examples are Mike Wright's CYC and
     the Sherlock Holmes stories I have recently converted to DV80.
     Sometimes these large DV80 files are too big to fit into MYWORD on a
     Geneve, and they are certainly too big to completely fit into the
     memory available to 40 column 99/4A users.  Users of 40 column systems
     can use DM1000 or DSKU to view these files on screen because only
     little pieces are loaded into memory at one time, but the view leaves
     something to be desired.  Each 80 column line wraps around to a second
     line on the 40 column display and words are often split in odd places
     in the middle of a line. 
           
          If only 40 column users could load these very large DV80 files
     into the Funnelweb editor, or other version of Ti Writer.  Then the
     text could be viewed in 80 columns by scrolling left/right.  This can
     be done!  I did it with the CYC.  What you need to do is break the
     large DV80 files down into a series of smaller files, each small
     enough to fit into the TI Writer text buffer.  Here is how to do this. 
           
          The key is to use the format "number space number space filename"
     when using L(oad)F(ile), S(ave)F(ile), and P(rint)F(ile) to split the
     large DV80 file into smaller pieces.  This means, "The first line
     number of the text in the disk file or edit buffer, a space, the last
     line number of the text in the disk file or edit buffer, a space, the
     file name." Another thing to remember is that no version of TI Writer
     will handle line numbers greater then 9999.  I am going to assume you
     are using any version of the Funnelweb text editor to split a file
     called TEXT into smaller TI-Writer sized pieces.  These instructions
     will work with any other version of TI-Writer as well. 
          1- Put a disk with the large TEXT file in DSK1.  Put a blank
     initialized disk in DSK2.  (You can use any other drive numbers you
     if you want.). 
          2- Boot the Funnelweb text editor and from the command line type
     "LF" and <enter>.  Then type "0001 9999 DSK1.TEXT" for a file name,
     complete with spaces, and press <enter>.  TEXT will load into memory
     until you get a BUFFER FULL message. 
          3- From the command line goto the end of the text in memory by
     typing "E" or "9999" followed by <enter>. 
          4- Probably the text in memory ends in the middle of a sentence.
     Move backwards through the text until you find a convenient place
     to end the small text file you are about to create.  This can be at
     the end of a chapter, end of a paragraph, etc.  Note the last line
     number of the part you want to save.  Write it down.  Lets call it
     LASTNUMBER. 
          5- Go to the command line and type PF and <enter>. (If you use PF
     rather than SF, then the original LF name stays in memory when using
     Funnelweb).  Type "1 LASTNUMBER DSK2.TEXT-A" for the file name and
     press <enter>.  Of course LASTNUMBER is a line number, not the letters
     L A S T etc.  This will save the first chunk of your large DV80 file
     as a smaller DV80 file that will fit into TI-Writer's edit buffer. 
          6- Go to the command line and type "LF".  The previous LF name
     "0001 9999 DSK1.TEXT" should appear if you are using Funnelweb.
     Change this to "LASTNUMBER 9999 DSK1.TEXT" and press <enter>.  The
     computer count through the lines of the large file until it gets to
     line LASTNUMBER, and it will then load the next part of the large file
     into memory until you get a BUFFER FULL message. 
          7- Again go to the end of the text in memory by typing "E" or
     "9999" from the command line and pressing <enter>. 
          8- Move back through the text until you find a convenient end
     point (paragraph or chapter end) and write down this line number,
     calling it NEWLASTNUMBER. 
          9- Go back to the command line, type "PF" and <enter>, and type
     "1 NEWLASTNUMBER DSK2.TEXT-B" as the next file name before pressing
     enter. 
          10- This is important!  You have to calculate the starting line
     number at which you will begin loading in the next segment of your
     large TEXT file.  Use the formula LASTNUMBER = LASTNUMBER +
     NEWLASTNUMBER.  Add these two numbers together to get the next
     LASTNUMBER. 
          11- Go to step 6 above and repeat steps 6-10 as many times as are
     needed to split TEXT up into TEXT-A, TEXT-B, TEXT-C, TEXT-D etc. 
           
          This is how I converted the BIBLE and the CYC into small files
     after using PC TRANSVER to convert large text files on a 360K IBM disk
     to a DSDD TI disk.  You may want to do the same thing with some of the
     Sherlock Holmes stories and other book length manuscripts that are
     appearing in the Lima User Group software library.
