Example SMC

--This program will demonstrate the LastIndexOf method. 

        
--File location path assigned to location string variable
location = "/mnt/SMC/custom"
--Opens a binary file name called "myfile" in write mode
file1 = File.OpenBinaryFile(location.."/myfile", FileMode.Write) 
--Write "ScanMaster ScanScript" string to "myfile" 
file1.Write(String.GetBytes("ScanMaster ScanScript"))
--Close the written file
file1.Close() 
f1= File.OpenBinaryFile(location.."/myfile", FileMode.Read)    
-- Read the whole file and return as byte array
readFile = f1.ReadToEnd()
--Display the file size
Report(f1.Length()) 
--Display the contents of the file
Report(readFile.GetString()) 
--Display the index of "c" in the specified string
Report(string.LastIndexOf(readFile.GetString(),"c"))
