Each namespace to be used in a PAscript program must be referenced, just like libraries, with the keyword using above the keyword program.

The individual elements of the namespace must be appended to each other using a colon (:).

Use as many using expressions the PAscript program requires.

Example

using  KA:TS:Engines:Combustion  /* namespace for using classes Cylinder 
and Power */
using  KA:TS:Engines:Electric  /* name space for using classes Capacity
and Power */
Program
  ...
endprogram
