Create a text field and two buttons, one for coverting to binary and another for converting to original form.

--Logic for converting to Binary. --******************************* global charlist -- list in which each character entered is stored as a seperate element. global cnt -- cnt to keep track of total caharacters entered into a text field. global binlist -- list which stores the binary value of each character. global templist -- list used for temporary storage. global bin -- flag set as soon as the entered text is converted to binary. global dec -- flag set as soon as the binary form is converted back to original. property tempvar -- variable used to store each character from the list during each repetion of the loop. property remd -- remainder value during division. property totchars -- total number of values in the binlist. on mouseUp -- Mouseup on a button    if bin = 0 then     if the text of field "entext" = empty then       alert "Please enter text"       exit     else       binlist = []       templist = []       charlist = []       cnt = the number of chars of field "entext"       repeat with i = 1 to cnt         append charlist, chartonum(char i of field "entext")         updatestage       end repeat       repeat with x = 1 to cnt         tempvar = charlist[x]         put tempvar         repeat while tempvar > 1           remd = tempvar mod 2           append templist, remd           put remd before field "remder"           updatestage           tempvar = tempvar / 2         end repeat      -- The field "remder" is used to temporarily store the binary values during processing.         put tempvar before field "remder"         templist = []         templist[x] = the text of field "remder"         append binlist, templist[x]         put binlist         set the text of field "remder" to empty       end repeat       set the text of field "entext" to empty       totchars = count(binlist)       repeat with s = 1 to totchars         put binlist[s] after field "entext"         updatestage       end repeat       bin = 1       dec = 0     end if   else     nothing   end if end --************************************************************ --Conversion from Binary to Original text --*************************************** global binlist global sumtot -- variable used to calculate the sum total of power values. global expo -- variable used to store successive exponential values. global bin global dec property tch -- total number of characters in the binlist. property tchars -- total number of characters stored in the temporary field "bintext" property t on mouseUp   if dec = 0 then     tch = count(binlist)     set the text of field "entext" to empty     repeat with x = 1 to tch       put binlist[x] into field "bintext"       tchars = the number of chars of field "bintext"       repeat with y = tchars down to 1         t = value(char y of field "bintext") * (power(2,expo))         sumtot = sumtot + t         expo = expo + 1         updatestage       end repeat       put numtochar(integer(sumtot)) after field "entext"       sumtot = 0       expo = 0     end repeat     dec = 1     bin = 0   else     nothing   end if end
