Rev 10.3 is a minor release for our newer software. In the past, a comi file must exist for any program to function. This is no longer the case. If a file, ROOT.COMI exist, then the commands in it will be executed. If the file does not exist, then the program will automatically query to terminal for information. This was implemented by adding two new options on the &EXEC command, -ICOMIN and -IAUXIN. With these options, the failure of the specified file to exist is not an error.

With this release, one can now consider the effect of forward speed on the frequency domain results.

The concept of string functions has become so popular that to cope with the increased demand, there were major changes here. First, many of the old ones were combined into several new ones. In particular, all of the old string functions dealing with numbers (&SIN, &SQRT, etc) have been deleted. In their place, a new string function &NUMBER has been added. This new function affords all of the capabilities previously, and has many more capabilities. In the past, there was a limit of 25 arguments to a string function. This has been removed.

A new feature of being able to use OCIME formulae to compute the wind and current forces on a tanker has been added, and a new command, ED_ELEMENT, has been added to the MEDIT menu. This command allows one to "edit" the properties of selected elements without having to totally redefine them. This feature is particularly useful for altering the K factors, flooding flags, etc. of elements. An option has been added to the PUNCH and FATIGUE commands which allows a user to override the joint classification. The API member and joint code checks have been revised to conform to the 18th edition of RP2A. Finally, the wind force on {{all}} of the load attributes is considered for wind heeling arms. In the past, only load group wind areas were considered.
