Hi, The X command/statement I use to execute some .bat files does not work anymore, It was working in the past. This condition applies to cmd commands, like <<X "del c:\test.txt";>> or <<X "c:\test\test_1\sample.bat">>. You can find the details below. Thanks. /* >>>> CODE_BLOCK_1 */ options noxwait noxsync; data _null_;   /*1.expression*/   rc1 = system('del D:\BAT_TEST\b.txt');   put rc1=;   /*2.expression*/   rc2 = system('notepad');   put rc2=;   /*3.expression*/   rc3=system("cmd");   put rc3=;   /*4.expression*/   rc4 = system("copy D:\BAT_TEST\a.txt D:\BAT_TEST\b.txt");   put rc4=;   /*5.expression*/   rc5 = system("notepad_2");   put rc5=; run; /* >>>> CODE_BLOCK_1 DOES NOT WORK >>>> 2. and 3. expression work , they open notepad and cmd applications >>>> but 1. and 4. expression do not work.

But only difference between 5. expression   and 2. expression is wrong application definition. I have added an "_2" string to "notepad".   I mean there is no different error code like "notepad_2 application was not found" etc... >>>> Log details are below   rc1=-2147475449   rc2=0   rc3=0   rc4=-2147475449   rc5=-2147475449   NOTE: DATA statement used (Total process time):        real time           0.12 seconds        user cpu time       0.03 seconds        system cpu time     0.04 seconds        memory              274.96k        OS Memory           29416.00k        Timestamp           12/19/2014 12:45:06 PM        Step Count                        116  Switch Count  0 >>>> In the conf. file XCMD option is set like -XCMD >>>> Log details are below   %put XCMD Value = %sysfunc(getoption(noxcmd));   XCMD Value = XCMD */ /* >>>> CODE_BLOCK_2 */ x 'del D:\BAT_TEST\b.txt'; /* >>>> CODE_BLOCK_2 DOES NOT WORK >>>> Result is same as CODE_BLOCK_1 >>>> Log details are below   1368  x 'del D:\BAT_TEST\b.txt'   1368!                          ; */ /* >>>> CODE_BLOCK_3 */ filename test 'D:\BAT_TEST\b.txt'; data _null_;    rc=fdelete('test');    put rc=;    msg=sysmsg();    put msg=; run; /* >>>> CODE_BLOCK_3 WORKS FINE >>>> It deletes the file(D:\BAT_TEST\b.txt) >>>> Log details are below   06  filename test 'D:\BAT_TEST\a.txt';   1307  data _null_;   1308     rc=fdelete('test');   1309     put rc=;   1310     msg=sysmsg();   1311     put msg=;   1312  run;   rc=0   msg=   NOTE: DATA statement used (Total process time):        real time           0.00 seconds        user cpu time       0.00 seconds        system cpu time     0.01 seconds        memory              256.00k        OS Memory           29416.00k        Timestamp           12/19/2014 11:12:15 AM        Step Count                        104  Switch Count  0 */ /* >>>> CODE_BLOCK_4 */ x notepad; /* >>>> CODE_BLOCK_4 WORKS FINE >>>> It opens notepad.exe >>>> Log details are below   1385  x notepad   1385!          ; */ ...
