To understand the general flow of events in the use of Entry, we'll construct a file containing two stand descriptions, one we will enter by hand, and one we will copy from another stand description file. To follow this on your own computer, have a copy of the stand description file "demo.sd" from the release disk of the CACTOS or CRYPTOS system. We will copy this stand description to our new file. We will start our tutorial with these steps: 1. Start the program by typing "ENTRY" [Enter] at the operating system prompt. 2. Since you are creating a new file, type in a file name that does not already exist. To see a list of the files on the disk, type a question mark "?" [Enter]. Use the name "NEWFILE.SD" for the new stand description file. (The ".sd" suffix is the standard ending for stand description files used by CACTOS and CRYPTOS.) The message File does not exist, open new file (y / n)? Type "y" [Enter] to create a new file. 3. You should now see the prompt ARE YOU ENTERING (0)LCR OR (1)HTCB:0 Type [Enter] to accept the default (live crown ratio). 4. When asked WHAT KIND OF FILE ARE YOU CREATING: 1 type [Enter] to accept the default ("1" for CACTOS). 5. You now have a blank stand description file and the screen shows the list or 14 species codes possible. You can now enter the site index and age (optional) for each species present.To begin adding header information, type "A" [Enter] at the command prompt. This puts the cursor at the label field. Enter a label for this stand description. Any label up to 20 characters may be entered. Then hit [Enter] or [tab] key to move to the next field. You can go backwards as well by using the shift-Tab keys. Use the Tab and shift-Tab keys to move to the ELEVATION and GROWTH YEARS fields, and enter suitable information in those fields (e.g., 3000 for elevation and 4.5 for growth years). You can also move to the site and age fields using the same keys. The Up and Down keys work for moving in the vertical direction just as the tab and backtab keys work in the horizontal. You can move through the site and age fields, entering site indices and ages for those species that you plan to enter tree records. Hit the Tab key at any time to stop editing and return to the command line. 6. Type "\" [Enter] to toggle to the tree editing screen, where you will find the stand description label, file name, tree information column headings and a list of commands. Type "3" [Enter] to see the species codes. We are now ready to enter the tree data. 7. Type "a" [Enter] to add tree records. Now, use the tab and arrow keys to see what happens and to find out how to move about and enter data. Fill in tree species number, DBH, total height, live crown ratio, and tree expansion. 8. To edit an entry, simply move back to it using the tab, backtab, and/or arrow keys and correct the entry. 9. When finished entering 4 or 5 trees, use the F2 key to go to the command line. 10. We now create a second stand description on the file "newfile.sd" by copying the stand description from the file "demo.sd" First, toggle bact to the header screen by typing " \ " [Enter] and type "f demo.sd" [Enter]. You now have two files open, "newfile.sd" and "demo.sd" and the file counter will show "FILE002/002", that is there are two files loaded and you are looking at the second file. 11. Start the copy procedure by typing "c" [Enter]. Now select the number of the file that you want to copy the current stand description to by entering "1" [Enter]. The copy process is very fast, so you are probably now back in the header screen of demo.sd. 12. Type "=1" [Enter] to move back to file #1, "newfile.sd", and you will see the information entered in the first few steps. Type "+&" [Enter] to move forward to the next stand description. You should see the same header information from demo.sd. Note also that the file and plot counters have changed in the lower right corner of the screen. 13. Type "q" [Enter] to save and quit our new stand description file. (If you do not want to save this file, type "q!" [Enter] ). Now type "x!" ( to exit the program entirely, not saving demo.sd (it wasn't changed, and will not be deleted). You can now use the new stand description in batch mode of either CACTOS or CRYPTOS. See the appropriate user's guide for information on batch operation. SAMPLE STAND DESCRIPTION FILE The following stand description example is of the format used in both CACTOS and CRYPTOS. It can be used in either since the species codes are all less than 8. Follow this example line by line with the description in the main text above.
