Double click on a variable, or select a variable and click on the Variable Properties 
icon in the File Definition toolbar.
Variable Name - The name of the variable.
Data Type - The variable type, A - Alpha, N - Numeric, or W – Wide.
Length - The length of the variable.
Dimension - If this data is to occur more than once, then this is the maximum number of elements allowed in the array.
Display Mask - The default display mask of the variable when displayed in a function.
Help Message - Help message for this variable, to be displayed when requested.
Default Tag Name - A default tag name is generated for the variable, based upon the variable name. You can amend this as required. When the variable is used in a function it will be given this tag by default (the tag name will automatically be de-duplicated at that point if necessary).
Default Object Type - The default object type for this variable – for example, Editbox, Checkbox, Listbox. Select from the drop-down list.
Click to the right of the field 
to access the tabbed Property Sheet for the selected object type. Any values that you enter in the Property Sheet will be used as the default properties whenever this variable is used in within a screen function. This is a powerful feature - for example, an editbox for which the data source is CUSTOMER_NAME could always, by default, call a Customer Selection screen. See the Events tab on the editbox property sheet and the information on global components.
Short Prompt/Long Prompt - Used in Forms Designer.
Database - This section is for non-PROISAM files only.
External Type - The external storage type for the variable.
Format - The external storage format for the variable.
Permit Null - If checked then null is allowed for this variable.
