1. Preparing a working copy of PC-PLOT                
                             
1.0 Overview-creating a working copy of PC-PLOT-IV        
                             
This section shows how to create a working copy of PC-PLOT-IV. Follow these directions to create a copy and save the master for backup. 
                             
1.1 Copying needed program files                  
                             
There are two batch files on the master PC-PLOT-IV diskette which will automate the process of copying the program files needed to run PC-PLOT-IV. The following files are needed to run PC-PLOT-IV and to test your setup of the program: 
                             
  PCPLOT.EXE   CHAPLIN   PCPLOT.HLP   COLORSYLT   TEK4105.PIC(-IV+)   
                             
1.11 Floppy disk based systems                     
                             
If your system does not contain a fixed disk or if you want to run PC-PLOT-IV from a floppy disk, you will have to prepare a disk to receive the program files. You should start out with a freshly formatted diskette. 
                             
Remove your PC-DOS system diskette from drive A: and insert your master PC-PLOT-IV diskette. Put a freshly formatted diskette in drive B and enter the following command to copy the needed files from diskette A: to B: 
                             
      A>FLOPPY<cr>                      
                             
The needed files will be copied to the diskette in drive B:. which will become your PC-PLOT-IV working diskette. Affix a label to the diskette with the legend: 
                             
      PC-PLOT-IV SIN xxxxx   Corwright 1987 MicroPlot Systems         
                             
    The serial number is REQUIRED for technical assistance from 1VlicroPlot.     
                             
You now have a complete copy of PC-PLOT-IV. Go on to section 2 to verify that your hardware is set up properly before operating PC-PLOT-IV. 
                             
1.12 Fixed disk- based systems                    
                             
If you will be running PC-PLOT-IV on a system which has a fixed disk, you will want to create a subdirectory for it. 
     
Creating a subdirectory for PC-PLOT 		            
                             
If you are copying the files from the floppy disk in A: to a fixed disk, the FIXED batch program assumes that it is drive C:. The FIXED program copies the files into the current directory of your fixed disk. If you want to create a separate subdirectory for 
PC-PLOT, you will need to do so before continuing. If your fixed disk is not drive C, you will have to copy the files manually since the FIXED batch file assumes 
drive C. 
                             
      To create a PCPLOT subdirectory, enter the following commands:       
                             
      C>cd <cr>   Switch to root directory               
                             
      C>mdPCPLOT<cr> Create \PCPLOT subdirectory           
  C>cd\PCPLOT<cr> Change to \PCPLOT subdirectory       
                         
PC-PLOT-IV has a facility which allows it to be run from any subdirectory and always use the setup data files in the subdirectory containing the program. 
                         
PC-DOS allows the user to define where the program loader will look for a file if it cannot be found in the current subdirectory. This is accomplished with the PATH command which is usually put in the AUTOEXEC.BAT startup file. For example, if you have several subdirectories which are named NORTON, UTILITIES, and EDIT, you may have a path statement which specifies: 
                         
  PATH=\NORTON;\UTILITIES;\EDIT;\ (no spaces in PATH command)   
                         
The path statement instructs PC-DOS to look in the currently used subdirectory for a program, in NORTON, UTILITIES, EDIT, and in the ROOT subdirectories. You should add your subdirectory which contains PC-PLOT-IV to the PATH declaration. If you do not have a PATH declaration, you will want to create one with the following command: 
                         
  C>CD <cr>                                              switch to root directory 
C>COPY CON AUTOEXEC.BAT<cr>  createAUTOEXEC file 
PATH=C:\PCPLOT\<cr> 		    
  ^Z<cr>                                                    depress ctrl-Z         
  C>                                                            file created           
                         
If you already have an AUTOEXEC.BAT file, either add to the path statement that is already there or add the following statement: 
                         
  PATH=C:\PCPLOT\<cr>                     
                         
Additionally, a program must be passed information in the PC-DOS environment area which tells it where the data files which are used with the program are to be found. This is accomplished with the PC-DOS SET command. Assuming that you copied PC-PLOT-IV into the PCPLOT subdirectory, insert the following command in your AUTOEXEC.BAT file: 
                         
  SET PCPLOT=C:\PCPLOT\                   
                         
When PC-PLOT-IV first starts up, it examines the PC-DOS environment area to see if there is a a string associated with the name 'PCPLOT'. If there is, it is copied into the PC-PLOT-IV string area to be used with the following files: 
                         
  PCPLOT.SET   Setup data file               
  PCPLOT.HLP   Help data file                 
  xxxxxx.PCS   Script files to connect to host             
                         
Put the master PC-PLOT-IV diskette in drive A: and enter the following command to copy the needed files: 
                         
  C>A:FIXED<cr>                       
                         
The procedure for creating a fixed disk working copy of PC-PLOT-IV is now complete. Go on to section 2 to verify that your hardware is set up properly before operating PC-PLOT-IV.
