Answer / Raju Shah
To delete a file using SQR, you can use the built-in system function called 'SYSTEM.FILE_DELETE'. Here's an example of a simple SQR program that deletes a file:nnPROGRAM-ID: DELETE_FILE.nPARAM1 PIC X(80).nnDATA DIVISION.ndw-main SECTION.ndw-main.010 PROCEDURE SECTION.nBEGIN PROCESS.n MOVE 'YOUR_FILE_NAME' TO PARAM1 WITH ERROR.n IF SYSTEM.FILE_EXISTS(PARAM1) THENn CALL SYSTEM.FILE_DELETE(PARAM1).n DISPLAY 'File has been deleted successfully.'.n ELSEn DISPLAY 'The specified file does not exist.'.n END-IF.nEND PROCESS.ndw-main.998 EXIT SECTION.nEXECUTE PROGRAM DELETE_FILE USING 'YOUR_FILE_NAME'.
