*/*/*¢ Download Doctor ¢ (Will be found on this disk under¢ the name "DLFILSPL.OBJ") By Matthew¢ Gilarde-Reprinted by the OL' HACKERS¢ A.U.G. 8 BIT, NY¢¢ Notice: This program was written¢ using Action!. Action! is a trademark¢ of Action Computer Services.¢¢ Download Doctor (DLDR), or¢ DLFILSPL.OBJ, is a program that¢ allows you to strip extra bytes off a¢ file which was transferred using¢ XModem. It also can convert Ascii¢ carriage return/line feed codes to¢ Atascii EOLs and vice versa, and¢ split large text files into separate¢ smaller files. ** ¢ To load DLDR simply go to Dos and¢ binary load DLDOCTOR.OBJ. The program¢ uses only "legal" CIO calls and¢ should work with any Dos. When run,¢ the main menu appears. Simply press¢ the letter of the option you want to¢ use. You will be asked to provide¢ the name of the file you want to work¢ on and the drive to which DLDR will¢ write the output file. Each option¢ will add a different extender to the¢ name, so that you know what was done¢ to the file. Make sure you have¢ enough room on the destination disk¢ for the output file. If you are¢ using one drive, you will be prompted¢ to swap disks as necessary. ¢ The options are explained below: ¢¢ ** Strip File Method #1 - This¢ option will strip the excess bytes¢ from a file downloaded with XModem. ¢ The output file will have the¢ extender "ST1". This command works¢ by finding the last byte of the file¢ and then removing bytes until it¢ finds a byte that does not match. It¢ then saves the file without the extra¢ bytes. ¢ ** Strip File Method #2 - This¢ option is similar to #1 above, except¢ that it creates a file one byte¢ longer, since the byte stripped may¢ be part of the file. The output file¢ is given the extender "ST2".¢¢ ** Strip File - Manual - When¢ you select this option, the file is¢ loaded and you are shown the last 128¢ bytes in a window. Move the cursor¢ within the window until it is over¢ the byte where you want to begin¢ stripping, and then press RETURN. ¢ The byte the cursor is on and all¢ following bytes will be removed. The¢ output file has the extender "ST3".¢¢ ** Ascii To Atascii Conv. - This¢ command will read through the file¢ and change CR/LF (or LF/CR)¢ combinations to EOLs. The current¢ byte count is shown in a window. The¢ output file is given the extender¢ "ATA".¢¢ ** Atascii To Ascii Conv. - This¢ command will read through the file¢ and change EOLs to Ascii CR/LFs. The¢ output file is given the extender¢ "ASC".¢¢ ** Split File - This command¢ divides a large file into 1K-16K¢ sections. The program will ask how¢ big you want each section to be.¢ Pressing RETURN gives the default¢ value of 16K. Each section will be¢ saved with an extender of "Pnn" where¢ "nn" is the section number (0-99). ¢ This command is really only useful¢ with text files, but will work with¢ all file types.¢¢ ** Set Default Drive - This¢ command lets you set the drive that¢ filename prompts will default to. ¢ This makes it easier to use the¢ program with files in a ramdisk. ¢ Just set the default drive to the¢ number of your ramdisk and you won't¢ have to change the drive number when¢ asked for a filename.¢¢ ** Disk Directory 1-8 - Pressing¢ a number 1-8 will allow you to view¢ the directory of that drive. You¢ will be asked for a mask. If you¢ want to see all files, just press¢ RETURN.¢¢ ** Mini-Dos Menu - This command¢ will take you to another menu that¢ allows you to erase, lock, unlock,¢ rename and copy files. You can also¢ format a disk (single density only). ¢ To return to the main menu, press¢ 'H'.¢ ** ** Notes ** **¢ 1. If you are stripping a file¢ and get the message "File can not be¢ stripped", press CTRL-B at the main¢ menu and try again. This will change¢ the buffer size so there will enough¢ data in the buffer for the strip¢ routines to work (they require at¢ least 128 bytes in the buffer).¢ 2. Wildcards are allowed in the¢ input filename, and all files¢ matching the filename will be worked¢ on. For example, if you enter¢ '*.OBJ' as the input file for a¢ command, any file with an '.OBJ'¢ extender will be manipulated. The¢ copy command does NOT allow¢ wildcards.¢ 3. If you have two files with¢ the same filename but different¢ extenders, and try to do the same¢ operation on both, the first one will¢ be written over. For example, if you¢ strip TEST1.OBJ and TEST1.DOC, both¢ will be written to TEST1.ST1. To¢ avoid this, make sure all files have¢ unique filenames.¢ 4. You can abort any command by¢ pressing ESCAPE at any prompt that¢ requires you to press a key. You can¢ not stop a command at a prompt that¢ asks you to press START.¢ =-=END=-=¢
