InputFile and PrintFile Statements The Comet32 Compiler and Runtime support very long strings. These statements allow you to manipulate a whole text file with one string.

PrintFile(LUN)string$ 
InputFIle(LUN)string$ 

An Example:

! Declare Function
String Ebcdic2Ascii(Instring$)
! Declare 2 Dynamic strings
length Dynamic & local EbcdicString$ AsciiString$
   clear
   print(et)

	 close(1) & open(1)'ebcdic.txt'          ! Input file containing Ebcdic
	 close(2) & open(2)'ascii.txt'           ! Output file for Ascii text
	 
	 InputFile(1)EbcdicString$               ! Read whole file into the string
   
   AsciiFile$ = Ebcdic2Ascii(EbcdicString$)      ! Translate it
   printfile(2)AsciiString$                      ! Write whole text file with one statement
done:
   print 'done'
   wait
   stop			
   end
! This is a user defined string function        
String Ebcdic2Ascii(Instring$)    		 ! Instring is by reference since it is not declared in the function
   length 256 & local table$
   length dynamic & local a$
   length 5.0 & local i l
