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

["Bob Crothers" <bob@xxxxxxxxxxxxxx>]

Here is what I use:

/* * * * * * * * * * * * * * * * * * * * * * * * * * * * */    
 /*                                                       */    
 /* cpycharstr - copy character buffer to a string.       */    
 /*                                                       */    
 /* * * * * * * * * * * * * * * * * * * * * * * * * * * * */    
                                                                
 void cpycharstr(char *ToBuf, char *FrmBuf, int FrmLen)         
 {                                                              
 int x;                                                         
                                                                
 memcpy(ToBuf, FrmBuf, FrmLen);                                 
                                                                
 ToBuf[FrmLen] = 0;                                             
                                                                
 for (x=strlen(ToBuf) - 1; x >= 0 && ToBuf[x] == ' '; x--)      
   ToBuf[x] = 0;                                                
                                                                
 return;                                                        
 }
