-
- MATHCAD DOCUMENTS
-
- The MathCAD Auxiliary Disk contains many sample documents. You can
- load these documents into MathCAD to see some ways to use MathCAD's
- features.
-
- See the file DIRECTRY.MCD for a list of these documents.
-
- UNITS DOCUMENTS
-
- The MathCAD Auxiliary Disk includes three files that contain unit
- conversions.
-
- CGS.MCD contains unit conversions in the cgs system, based on
- centimeters, grams, and seconds. All units, including electrical
- units, are defined in terms of these base units.
-
- MKS.MCD contains unit conversions in the MKS system, based on
- meters, kilograms, seconds, and coulombs.
-
- USCUSTOM.MCD contains unit conversions based on the U.S. Customary
- units of feet, pounds (mass), seconds, and coulombs.
-
- You can add these conversions into files you create, or append
- them to the end of your files using the MathCAD append
- command.
-
- PROGRAM NOTES
- =============
-
- REDISPLAY COMMAND
-
- If you suspect that the MathCAD display screen is not accurately
- reflecting the state of a document, or if equations on screen
- have gaps or overlap one another, use the redisplay command by
- pressing [Ctrl]R. This redisplays the whole screen.
-
- Here are some actions that can cause the display to have gaps or
- unreadable parts:
-
- 1. Regions that overlap one another on the screen.
-
- 2. Error messages from an equation or plot that coincide
- on screen with other regions.
-
- 3. Cutting and pasting equations that overlap one another.
-
- None of these problems can cause computational errors; they
- affect the display only. When the information on the screen is
- unclear, press [Ctrl]R to redisplay everything.
-
- PRINTING DOCUMENTS
-
- If your printer works with other programs but not with MathCAD,
- MathCAD may be having difficulty communicating with your printer.
- Check the following:
-
- PARALLEL PRINTERS: Specify PRN or LPT1 as the printer device.
- (Specify LPT2 if the printer is on the second parallel port.
-
- SERIAL PRINTERS: First execute the following DOS commands:
-
- MODE COM1: 9600,N,8,1,P (or other parameters as
- appropriate for printer)
- MODE LPT1:= COM1
-
- Then, when MathCAD prompts for a printer device, specify PRN.
-
- PLOTTERS: First execute the following DOS command:
-
- MODE COM1: 9600,N,8,1,P (see your plotter manual to
- make sure this is correct.)
-
- Then, when MathCAD prompts for a printer device, specify COM1. DO
- NOT use LPT1 or PRN, even if you have redirected them to COM1.
-
- WHAT TO DO IF MATHCAD CANNOT PRINT
-
- First, check that your printer is compatible with a model that
- MathCAD supports. See the description of printing in the User's
- Guide and the descriptions of each printer driver in the printed
- Release Notes in the disk pocket of your package.
-
- If MathCAD cannot print directly, try printing to a file as follows:
-
- 1. Print the document to a file. Type [Esc] print [Enter].
- When MathCAD prompts you for a print area, press [Enter].
- Then, in place of the printer device, specify a filename like
- OUTPUT.PRN.
-
- 2. Save your document and exit MathCAD by pressing [Ctrl]Q.
-
- 3. At the DOS prompt, type:
-
- COPY /B OUTPUT.PRN PRN
-
- This sends the print file to the printer. Substitute the
- filename you used in step 1 for OUTPUT.PRN and the name of
- the port to which your printer is attached (for example,
- LPT1 or COM1) for PRN.
-
- REPLACE COMMAND
-
- MathCAD will not always recalculate equations as necessary
- after using the replace command ([Ctrl][F6]). After a replace
- command, do a process command to ensure that the calculations in
- the document are up to date.
-
- AT & T 6300 SERIES COMPUTERS
-
- To run in high-resolution mode (640x400 color or monochrome) on an
- AT&T 6300 series computer, type:
-
- MCAD /A
-
- If you do not type /A, MathCAD runs in CGA-emulation mode (640x200
- monochrome).
-
- L/I/M EXPANDED MEMORY LIMITATION
-
- In MathCAD 2.00, MathCAD uses at most 1 megabyte of available
- expanded memory.
