Writing to Sequential Dataset in COBOL makes it an inaccesible binary

The following code should take a sequential dataset as input through DDINPUT describing bank accounts and output a sequential dataset through DDOUTPUT with the names of those bank account owners with a balance greater than $8,500,000. But, as we are in Stack Overflow, it doesn't.

           COMPUTE RES = FUNCTION NUMVAL-C (ACCT-BALANCE).
           IF RES > 8500000
              DISPLAY "Adding " WS-FIRST-NAME " " WS-LAST-NAME "..."
              MOVE SPACES TO PRINT-ACC 
              MOVE WS-LAST-NAME    TO LAST-NAME-O
              MOVE WS-FIRST-NAME   TO FIRST-NAME-O

              WRITE PRINT-ACC
              END-IF.

The code gets right the name of the owners with balances greater than $8,500,000 but doesn't write properly as, when the output dataset is accessed, VS Code throws the following error:

cannot open file:zowe_path. Detail: File seems to be binary and cannot be opened as text.

I'm quite new at COBOL and I have no clue what I'm doing wrong when writing to output. Maybe the JCL is causing the problem:

//TOPACJCL  JOB 1,NOTIFY=&SYSUID
//***************************************************/
//COBRUN  EXEC IGYWCL
//COBOL.SYSIN  DD DSN=&SYSUID..SOURCE(TOPACCTS),DISP=SHR
//LKED.SYSLMOD DD DSN=&SYSUID..LOAD(TOPACCTS),DISP=SHR
//***************************************************/
// IF RC = 0 THEN
//***************************************************/
//RUN     EXEC PGM=TOPACCTS
//STEPLIB   DD DSN=&SYSUID..LOAD,DISP=SHR
//DDINPUT   DD DSN=MY.DATA(INPUTD),DISP=SHR
//DDOUTPUT  DD DSN=MY.DATA(OUTPUTD),DISP=SHR
//SYSOUT    DD SYSOUT=*,OUTLIM=15000
//CEEDUMP   DD DUMMY
//SYSUDUMP  DD DUMMY
//***************************************************/
// ELSE
// ENDIF

Hopefully you can help me as I've been trying to fix this for the past hours. Thanks in advance!

EDIT #1: Added "MOVE SPACES TO PRINT-ACC", still doesn't work.
