Modeleasy+ Release 5.2

Econometric Modeling & Computing Corporation is pleased to announce the release of Modeleasy+ 5.2. This release of Modeleasy+ has the new features shown below:

variable names of up to 200 characters;

new options for controlling model simulations;

improved methods of exchanging data with Excel;

many new commands.

Variable Names

A new facility, referred to as "long names", has been introduced in Modeleasy+ 5.2. This facility allows the user to define variables with names of up to 200 characters, thus removing the old limitation of 8 character variable names. In order to be compatible with previous releases, Modeleasy+ 5.2 is being distributed with the long name facility turned off. In order to define variable names longer than 8 characters, the user must first turn the long name facility on by using the LONGNAMES command. This may be automated by placing the LONGNAMES command into the START.USE file used when Modeleasy+ is started.

For a more complete discussion of the long name facility, refer to the Enhancements page

New Options

A new simulation capability has been introduced in Modeleasy+ 5.2. This capability allows the user to specify bounds on a variable and how the variable should be treated if a bound has been exceeded during the solution process. The BUILDMODEL command now has an option which allows the user to specify that one or more variables may be subject to bounds during the simulation of the model. The bounds on the variables may be specified using the SIMOPTION command. New options have been added to the SIMOPTION command which allow the user to specify the convergence criterion of the rational expectations cycle (RECONVERGE) along with the maximum number of iterations of the rational expectations cycle (REITERLIMIT).

For a more complete description of how to limit a variable during simulation, refer to the Enhancements page.

Exchange Data

The Windows version of Modeleasy+ 5.2 has a facility to communicate directly with the Windows Clipboard. The words TOCLIPBOARD and CLIPBOARD can be used to place data on the Windows Clipboard or retrieve data from the Windows Clipboard, respectively. These words are especially useful in establishing a data communication channel between Modeleasy+ and a spreadsheet program such as Excel. To send data from Modeleasy+ to Excel, the TOCLIPBOARD command is used to place the data on the Windows Clipboard. This data can then be "pasted" into Excel using standard tools. To send data from Excel to Modeleasy+, the data can be "copied" or "cut" in Excel using standard tools. This data can then be retrieved from the Windows Clipboard using the CLIPBOARD command.

New Commands

Many new commands have been introduced in Modeleasy+ 5.2. Some of these commands, along with a short description, are shown below. For a more complete description of the use of these commands, refer to the on-line Help document.

	CLIPBOARD retrieves data from the Windows Clipboard.
	DATEYRPP creates a date array in the format YYYYPP.
	DISAGGR interpolates a set of equally spaced data.
	GROUPDEVIATION returns deviations of grouped data.
	GROUPOPERATION operates on groups of elements in an array.
	LONGNAMES controls the use of names with more than 8 characters.
	SCHUR returns the Schur form of a square matrix.
	TABIT is a modified version of TABULATE.
	TOCLIPBOARD places data on the Windows Clipboard.
	TSREN renames a list of time series.

These commands are in addition to the hundreds of commands previously available in Modeleasy+ 5.1.
