S=0 :Lateral Load

S>0 :Gravity Load
S=-2 :Quit Macro Definition
All member properties are define from left to right.
Story heights are defined from ground up: e.g., story1 story2 story3
The input parser ignores 'end-of-line' comments when numeric data is expected, but will not ignore blank lines or comments when descriptions are expected. e.g., Wind + Dead Load
