  Use of a command object under solution is one way. Start with:
  
  /post1
  
  set,first
  
  *get,nres,active,,set,nset ! number of results sets
  
  *get,ndmx,node,,num,maxd
  
  *dim,nodaldisp,array,nres,ndmx*3 ! for translation only or 6 if rots are needed
  
  then a do loop cycling through the result sets with *vget commands of the three nodal displacements. See *MWRITE for output of the parameter to a file.

  SET,FIRST
  
  NSEL,S,NODE,,141475,142273 !!!! 800 nodes
  
  NODENUMBER = 141475 !!! initial node number
  
  *DO,KK,1,800,1
  
  *VGET,RES,NODE,NODENUMBER,V,Y,,,4
  
  *CFOPEN,'MYFILE','CSV'
  
  *VWRITE,'NODAL','VELOCITIES'
  
  %I, %G
  
  *SET,NODENUMBER,NODENUMBER+1
  
  *ENDDO
  
  *CFCLOS
  
  is my code correct??? please help me out

  SET,LIST
  
  *DIM,VELY,ARRAY,3125,800 !!!!! FOR 800 NODES AT 3125 TIME STEPS
  
  NODENUMBER=141475 ! INITIAL NODE NUMBER
  
  *CFOPEN,VEL,CSV
  
  *DO,KK,1,800,1
  
  *VGET,VELY(1,KK),NODE,NODENUMBER,V,Y,,,4
  
  *VWRITE,VELY(1)
  
  (E15.
  
  NODENUMBER=NODENUMBER+1
  
  *ENDDO
  
  *CFCLOSE
  
  another code to extract results at 3125-time steps
  
  I am unable to write results to CSV file instead it is writing all zeros
  
  any help will be appreciated???
