One or more attributes with value may be specified in the same call.

Example

  set(LFONT=1, LDASHL=15);

Activates linefont 1 (dashed) and sets its dashlength to 15 millimeters. From now on lines will be dashed with dashlength 15.

Note that you can also use attributes in geometric procedures and part calls:

  poi_free(#5,vec(100,100):LEVEL=7,PFONT=1,PSIZE=5);

Overrides the default attribute settings and creates a point with font 1, size 5 and level 7. No other entities are affected.

  part(#5,my_part(my_parameters):PEN=2);

Loads my_part.MBO and executes the module with the default value of the PEN attribute set to 2. In effect the same as if the first line in the module was: set(PEN=2);

Comments

See also the set_basic() procedure which has the same syntax but basic effect.
