     I found this in the C/C++ runtime reference. Here's a snip:
     =======================================
1.2.204 system() -- Execute a Command




Format 


     #include <stdlib.h> 
     int system(const char *string); 


Description 


Language Level: ANSI 


Thread Safe: YES. However, the CL command processor and all CL commands are
NOT 
thread safe. Use this function with caution. 


The system() function passes the given string to the CL command processor
for 
processing. 


Return Value 


If passed a non-NULL pointer to a string, the system() function passes the 
argument to the CL command processor. The system() function returns zero if
the 
command is successful. If passed a NULL pointer to a string, system() 
returns -1, and the command processor is not called. If the command fails, 
system() returns 1. If the system() function fails, the global variable 
_EXCP_MSGID in <stddef.h> is set with the exception message ID. Your 
application should monitor for the return values of system().

Is there a place where one can "Easily" find what the valid values are for 
the return codes from API's
And what they mean?    I would suspect there is a correlation between what 
is returned in the 10i  return code and the 7 byte ErrorCode.  Right?   Can 
one just get alisting by API the valid 10i return codes and a description?
