PSZ buff = "C:\\OS2\\CMD.EXE\0/C Echo Hello!";

rc = DosExecPgm ( NULL,                 /* Object name buffer         */
                  0,                    /* len of object name buffer  */
                  EXEC_SYNC,            /* execute synchronously      */
                  buff,                 /* arguments                  */
                  NULL,                 /* environment                */
                  (PRESULTCODES)&exec_rc,       /* return codes       */
                  buff );               /* program to execute         */

Notice the \0 after the program name. The last argument to DosExecPgm
uses the first SZ from buff for the program name and 4th argument to
DosExecPgm uses the first SZ as argv<0> and the second SZ as the
arguments to the program!
