Command:	15.2
Alpha Alias:	Feature Desc
Description:	Defines a repeating feature description for the output of subsequent inversed figures
Data Format:	15.2 "Feature-Desc" ;
Problem:	Given area closures for two areas. Assign a repeating feature description for output of the closure information for each area.
Solution:	15.2 "Area Number" ;

Data Description

Command	15.2	Used to define a repeating feature description for output of all subsequent inversed figures. For example: '15.2 Lot ; 7 123 1 2 3 4 1 ;' will concatenate the string 'Lot' to the figure number identified by the 7 command and print the value in the output as 'Lot 123'. Note: The 15.2 command uses the absolute value of the figure number. Therefore, figure numbers should be positive. Beginning with Version 5, the figure number may be an alpha-numeric word such as 123a or CL_3rd_Street. This data is also exported as extended entity data during DXF export.
"Feature-Desc"	"Area Number"	Alpha-numeric string used to describe the subseqent figures inversed with the 6, 7, -7 and 8 commands. Must be delimited with double quotes. Note: Disable the repeating feature description for subsequent inversed figures by assigning the string a value of "".
End Command	;	All commands end with a semi-colon.
