/* RETURN CODE DESCRIPTION */
/* If the function is successful, the return value */
/* from WinExec identifies the instance of the */
/* loaded module. Otherwise, the return value is an */
/* error value between 0 and 32. */

/* 0 System was out of memory, executable */
/* file was corrupt, or relocations */
/* were invalid. */
/* 2 File was not found. */
/* 3 Path was not found. */
/* 5 Attempt was made to dynamically link */
/* to a task, or there was a sharing or */
/* network-protection error. */
/* 6 Library required separate data */
/* segments for each task. */
/* 8 There was insufficient memory to */
/* start the application. */
/* 10 Windows version was incorrect. */
/* 11 Executable file was invalid. Either */
