I had a text file with values as below

59, -65, 5, 5, 0, -65, 85, 90, -30, -30, -30, 60, -70, 10, 40, 40, 40, 45, 80, 80, 80, 85, 0

67, 5, -65, 0, -65, 90, -90, -50, -50, -50, -45, 20, -70, 0, -5, -10, -90, -90, -5, 85, 85, 0, -65

71, 15, -65, -30, -30, -30, -30, -30, -35, -35, -35, 0, -65, 30, -70, -10, -10, -10, 65, -65, -65, 0, 50

How should I read these values into an array in APDL ?

I tried using *vread but I am getting error.

/INQUIRE,rows,LINES,'file','txt'

*DIM,arr_data,ARRAY,rows,23

*VREAD,arr_data,'file','txt',' ',jik,23,rows,1,0

I am getting fallowing warning

In the graphical user interface, the VREAD command can only be executed

 from an external file such as /INPUT or *USE. The command is ignored.

Please can anyone share working code to read the above external data into an array in APDL ?

I am able to get desired array.

/INQUIRE,tot_keypoints,LINES,Keypointnumbers,txt
*DIM,KPOINT_NO,,tot_keypoints,2
*VRead,KPOINT_NO(1,1),Keypointnumbers,txt,,JIK,2,tot_keypoints
(2F6.0) ! I forget to specify this formate in the above code so I got error
!---------------------------------------------------------------------------------------------------------
*dim,KpArr,array,tot_keypoints
*DO,I,1,tot_keypoints
KpArr(I) = KPOINT_NO(I,1)
*ENDDO

As per my knowledge from APDL Codes for creating ARRAYs each row in the file should have same number of coloumns
So I saved the values of each row in a seperate file and implemented the above APDL CODE.

Data in each row of the above .txt file is saved in seperate files with the file named as file_59.txt , file_67.txt, file_71.txt, file_76.txt, file_82.txt.
Example: File file_82.txt has the fallowing colomn data.
82

Data contained in the file named "Keypointnumbers.txt" is given beolw:
59, 61
67, 41
71, 42
76, 48
82, 57
first coloumns represents number for iterating over files in the later steps
and second colomns represents the number of rows present in each file.
