2.  LOAD = num2: Select an external static load set.

•     num2: Set identification of at least one external load Bulk Data entry.

3.  OLOAD(SORT1,PRINT)=ALL: Request the form and type of applied load vector output.

4.  SUBTITLE= RecurDyn SIMULATION TIME = x.x: Define a subtitle that will appear on the second heading line of each page of pronter output.

5.  GRAV, SID, , A, N1,N2,N3: Define acceleration vectors for gravity or other acceleration loading.

•     SID: Set identification number. 

•     A: Acceleration vector scale factor. 

•     N1: the x – linear acceleration.  N1 = ACC_X
