Isn't the use of romex vs. conduit based on the use of the building and the number of floors the building? Meaning if the building is over 3 floors, it is required to be in conduit. Also if certain uses require conduit such as commercial garages with hazardous material, theaters, motion picture studios and more.ou kind of have it backwards in that NM cable is typically used in buildings that are easier to burn down -- perhaps there is a cause and effect here! Here is what the code says for uses permitted for NM cable: (1) One-and two-family dwellings.
So far, we have seen variables used to store and recall integer values. Variables can also store real numbers and strings. In order to allow a variable to store these other types of data, you must make sure the variable is recognized as a real or string variable. To name a real number variable, you must add a hash character (#) as the last character of the variable name.
A 'Dot Variable' is a variable to which has been pre-assigned a fixed value. The name derives from the setup of the variable in a document: [.VarName]. Note the period (dot) introducing the variable. See the box below for more samples of Dot Variable use. You might use a Dot Variable when you want to assign a variable to a specific value that is not likely to change. The Dot Variable, instead of 'hard text' is placed in the document. If the value changes you simply to change the 'value' once, not in each location where you might otherwise have hard coded a document.
