Customizing the metamodel : Keywords for USRPROPS : LINES
  
LINES
Sets the number of lines, in depth, for a property field.
Example
DEFINITION "Constructor" { CHAPTER " Desc., Formal Parm" GROUP "" { LAYOUT { COLS 2 TAB ALIGN OVER } PROPERTY "Formal Parameters" { KEY EDIT Text LENGTH 1020 } PROPERTY "Initializer List" { EDIT Text LENGTH 1000 LINES 4 }
This keyword is only useful if you want the space automatically provided to be much bigger or smaller than the default.
