INPUT

The INPUT statement allows the model to prompt the user for constants and layers (i.e., image channels on the database) which should be associated with layer variables.

 Syntax:    INPUT "text" #x;            | numerical constant
            INPUT "text" $x;            | character constant
            INPUT "text" %x;            | layer variable

 Example:   input "Enter layer for Tree Coverage: " %tree ;

Values entered by the user for a layer variable are checked to ensure the image channel exists on the database file.
