(1) Coding example

strStrName = "0123-4567-89AB-CDEF";    // Original string
strSearchStr = "-";                    // Search string
nStartPos = 0;
while(TRUE)
 // Gets the length of string to be extracted.
 nLength = AIT_FindSubStr(strStrName, strSearchStr, nStartPos);
 if (nLength == -1)
   // Sets the string to be extracted last.
   strSubString = strStrName;
   AIT_LogMessage("strSubString = " + strSubString);
   // Ends extraction of strings.
   break;
 else
   // Extracts a string.
   if (!AIT_GetSubStr(strSubString, strStrName, nStartPos, nLength))
     AIT_LogMessage("AIT_GetSubStr failed");
     break;
   else
     AIT_LogMessage("strSubString = " + strSubString);
   endif;
   // Deletes the extracted string from the original string.
   strStrName = AIT_StrLTrim(strStrName, strSubString);
   strStrName = AIT_StrLTrim(strStrName, strSearchStr);
   strSubString = "";
 endif;
loop;
// Value of strStrName changes from that before processing.
AIT_LogMessage("strStrName = " + strStrName);

(2) Results

The following shows the results output to RecDFile.log.

strSubString = 0123
strSubString = 4567
strSubString = 89AB
strSubString = CDEF
strStrName = CDEF
