IB Statements/InputFile and PrintFile
From CometWiki
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
end
String Ebcdic2Ascii(Instring$) ! Instring is by reference
