RE: [C400-L] Help Calling a C program From CL

["Ulrich, Kent" <Kent.Ulrich@xxxxxxxxxxxxxxx>]

Here is the function I use:
 void                   StrParm(char *Variable,      
                                const char *Argument,
                                const int  ArgLen)   
{                                                    
 int                    i;                           
                                                     
 strncpy(Variable, Argument, ArgLen);                
                                                     
/*  Strip trailing blanks. */                        
 for (i=ArgLen-1; (i>0 AND Variable[i] EQ ' '); --i) 
   Variable[i]='\0';                                 
} /* Endfunc StrParm. */

Thanks. Addind the null and removing the space fixed the problem.
Would you mind sharing the function you wrote ?

It seems that the CL can not easily read the stdout from the c code.
Is there a way that the CL can read the output into a variable ?

-Thanks
