With Units Data Type

MDSplus provides a with units data type which enables you to attach units to a value. A with units data item is a structure containing two "fields". The first field is the value and the second is the units. Each part of a with units data time can be either missing or a value of any other supported data type. General applications available at your site may assume some convention on the type of data each field contains (i.e. a units field that when evaluated returns DTYPE_T, a string).

A with units item can be created using the BUILD_WITH_UNITS or MAKE_WITH_UNITS functions. For example:

_mydata = BUILD_WITH_UNITS(42,"volts")

The following table lists some of the functions available for creating or accessing with units items:
