When you start the program, this is what you should see:
|
|
In Windows the program often starts with a narrow screen. You can change the width of the terminal screen by:
Information about the program version is displayed, followed by the EosFit7.6> command prompt.
All commands are entered by typing them in at the prompt.
All of the commands are grouped by usage. For example all of the features related to data handling and fitting (i.e. read, write, select, fit etc..) have been grouped together into one set of commands labeled "Data Handling and Fitting".
Sets of commands like "general", "EoS Input and Output" and "Advanced" are always available through all the program including each subroutine (i.e. isomeke and input).

System & Macro Commands |
TIME |
Includes the data and time in the command prompt. This is a toggle: use it a second time to remove the date and time from the prompt. |
RECORD |
Record commands in to a macro file, so that the sequence of commands can be repeated automatically with the macro command. Terminate recording by typing END |
|
MACRO |
Load and run a set of commands from a macro file |
|
END |
Only active when RECORD is being used; stops recording of commands to macro file. |
|
SYS |
Switch to operating system. After typing SYS, all subsequent commands will be sent directly to the operating system. |
|
PROG |
Only active after SYS has been typed. Exits from system, back to EosFit-7c program . |
|
DIR |
List files in current working directory (works just like dir in MS-DOS). |
|
CD |
Change working directory (works just like cd in MS-DOS). |
