Command Line Options
 Previous  Next
Concyl includes a command line interface that allow the user to control program operation and specify optional file names and directories for the input and output files.  There are two types of command line options:  switches and variables.  A switch requires no additional data, while a variable must be followed by an assigned value.  Each command line option begins with a - character.  Variables must be followed by an equal sign and the value.  Each command line option must be separated by at least one space.  Table 2 lists the available command line options.

The -if and -of command line variables are optional and have default values if they are not used. The default input file is "Concyl_Input.txt" and is located in the same directory as the Concyl executable.  The default output file is "Concyl_Output.txt" and will be written to the same directory as the Concyl executable. 
Several sample command line sessions are shown in Table 3 below.
