To get help about a parameter enter ?. Usually, this will give access to the help-library information for that parameter, for example,
BOX - Smoothing box size /3,3/ > ? BLOCK Parameters BOX() = _INTEGER (Read) The sizes (in pixels) of the rectangular box to be applied to smooth the data. These should be given in axis order. A value set to 1 indicates no smoothing along that axis. Thus, for example, BOX=[3,3,1] for a three-dimensional NDF would apply a 3x3-pixel filter to all its planes independently. If fewer values are supplied than the number of dimensions of the NDF, then the final value will be duplicated for the missing dimensions. The values given will be rounded up to positive odd integers, if necessary, to retain symmetry. BOX - Smoothing box size /3,3/ >
and then immediately reprompt you for the parameter. There are
occasions when information about the parameter is insufficient; you
may require to examine the examples or the description of related
parameters. This can be achieved by entering ?? to the prompt.
You can then delve anywhere in the help information. When you exit the
help system you're reprompted for the parameter.
