Introduction

Syntax aspects that affect some MiraMon Support Modules are explained here in a generic way.

Selection of one vertex Z coordinate in a 3D vectorial file with multiple height for each vertex


Internal date and hour format

For further information on dates and hours please refer to general considerations.


How to know what type of structuration algorithm use in some MSA? (optional modifier /ALGORITME=)

It is possible to choose between two algorithms for calculating the intersections between different vectorial elements: "direct algorithm" and "sweep algorithm".

Then,

If at the time of structuring a layer it is know that structuration will generate new points (ie, intersections are detected) is better to choose "escombratge". Otherwise, you can choose to "directe".


Decision for quantiles (optional modifier /MEDIANA_EMPAT=)

If an application performs the calculation of some quantile (such as the median, a quartile or a percentile), indicates the type of tiebreaker to be used for its calculation when the quantile position is between two values in the series. The criterion will also be applied when the mean of the absolute deviation around the median must be calculated (since it requires the median to be calculated). The calculation options are:

The default option is 1.
