Lawrence Software P.O. Box 1002 Smithville, Texas 78957 PC-Convert is a self documented program which converts Engineering Units from one form to another. It takes command line input (arguments), checks input for acceptability, and makes a conversion if possible. Syntax: convert is any real number is any available unit is an integer number See the following paragraphs for an explanation of the command line arguments. VALUE: The first command line argument can be any real number, positive or negative. PC-Convert will treat your input as a Pascal double precision number. Keep in mind the desired accuracy of your answer, ie., if two decimal place accuracy is acceptable in your answer, then five decimal place input is not necessary. UNITS: The second command line argument. For a list of available units, enter "convert" without command line arguments. A list of available units is provided with their correct abbreviations. The available units for this ShareWare version number only thirty. PRECISION: The third command line argument is optional, and the default is four, (4). If, by a combination of a large input value and/or a high requested precision, the result length exceeds the display capacity, an error message will be presented. In summary the following is a valid input: convert 100 psi 5 If the preceding command is entered, PC-Convert will convert 100 pounds per square inch to various other units with the result presented to five decimal place accuracy, (rounded off to the fifth decimal place). Effort has been made to disallow and correct improper input. For example, if you try to convert -15 psi, the program will reject the -15 and use -14.69595 which is the largest negative value possible in this case. Conversion factors were chosen from several sources. One thing learned while doing research for this program was the variance in conversion factors from source to source. Also, several errors were found and corrected in the beta version. User comments and suggestions are welcomed. For instant access to this program using a hard disk, the program file, convert.exe, should be placed in a directory which is in your path. My philosophy is to place all single file utility programs of this type and all program batch files in one directory. My path statement is set to this directory and this directory ONLY. I call it "BIN", (for BINary). This is the proven UNIX method. I have instant access, (from anywhere on the hard disk or floppies) to this program, to all other useful utilities, and to all application programs (via my program batch files). Finally, I am at a loss to set a value on registration. This program will be growing. My intent is to keep the registration cost nominal but commensurate with the state of development. If you find this program useful, please contact me regarding registration. Special versions are possible for your application. This program may be distributed and copied freely so long as it is not modified and this text file accompanies the executable file.
