- DIALOGBOX dialog_name ... ... [field_name field_type [field_list [enum_list] field_var default_value] | separator ] (n times) * Permits to construct a dialog box with editable fields. The box will appear in a window called dialog_name . The Gifa program will be blocked as long as the user has not closed the window. It will have two buttons at the button : Ok closes the form and resume the execution of Gifa Cancel closes the form, abort the command and generate an error The dialog is also composed en fields which appear one on each line in the window. A dialog can hold as many field as needed. Each field has : * a name field_name that will show on the left side of the field * a type field_type which is chosen in the following list : ( message, string, int, real, file, enum) message type of field have no other field, this kind of entries serves to put plain text in the dialog * All other type have a field_var entry which determines the name of the Gifa vairable in which the user input will be stored, and the default_value entry which determines the value of that variable when creating the form. string int real and file types of field have no other entry. They appear in the window as editable string. When the user hits return there, the content of the string is copied to the Gifa variable field_var. file entries will have a small arrow which permits to open a standard file dialog window. enum have an additional entry : enum_list.. This kind of field will appear as a pop up menu permitting to choose between the entries defined in the list : enum_list. This list is a single blank separated word, each item being separated with commas. The special entry separator is not associated to a variable, but permits to enter a separator in the dialog. The list is terminated with a star.

- DIM n (n=1 or 2) DIM is a context which equals 1 if you are processing one dimensional NMR spectra, 2 if you are processing two dimensional spectra and 3 if you are processing three dimensional spectra. Since 1D 2D and 3D data-sets are kept in different buffers, you can switch between this 3 modes freely, keeping the data-sets protected.

- DT->SVD size Calculates the Toeplitz rectangular matrix from the data and perform the singular value decomposition. size is the size of data used in the formation of Toeplitz matrix. This is the first step of the LP- SVD spectral analysis method. The same singular value decomposition can be used to perform forward and backward analysis.
