Character to ASCII to Character

Contents

This is an example that demonstrates how to convert a text string into its ASCII values. In this example, conversion will also create a log of how each loop in the example script shows with text character the computer has assigned a number, and how that number can be used to convert the number back into its original character.

Standard ASCII Table:

This is the Standard ASCII table for converting text to an ASCII value, and for using the Chr() function to convert the ASCII number to a text character.

ASCII Character Reference Table

Example:
VARIABLES: n, iTextLen, iCharNum, iChar Type: Integer VARIABLES: sText, sTxtChar,sTxtChar2, MyString Type: String ' Assign String to Convert Character Values sText = "<![CDATA[ xxxxxxx" ' Determine the Length of the String iTextLen = Len(sText) ' Clear the Working Output String MyString = "" ' Let TB show the ASCII Characters for the String For n = 1 TO iTextLen STEP 1 ' Get 1 Character from a String sTxtChar = mid( sText, n, 1 ) ' Convert Character to its ASCII Number iCharNum = ASCII(sTxtChar) ' Show What is happening on each cycle of the loop PRINT iCharNum," = ",sTxtChar ' Concatenate the results of the looping changes MyString = MyString + "Chr(" + AsString(iCharNum)+")+" Next ' n ' Remove the Last "+" from the created string iTextLen = Len(MyString) - 1 ' Update the created string without the "+" sign MyString = Left(MyString,iTextLen) ' Show processing Results PRINT MyString Results: The information shown below is the output of create when each character is converted to ASCII, and the text value that number illustrates. 60 = < 33 = ! 91 = [ 67 = C 68 = D 65 = A 84 = T 65 = A 91 = [ 32 = 120 = x 120 = x 120 = x 120 = x 120 = x 120 = x 120 = x Chr(60)+Chr(33)+Chr(91)+Chr(67)+Chr(68)+Chr(65)+Chr(84)+Chr(65)+Chr(91)+Chr(32)+Chr(120)+Chr(120)+Chr(120)+Chr(120)+Chr(120)+Chr(120)+Chr(120)

Example:

VARIABLES: n, iTextLen, iCharNum, iChar Type: Integer
VARIABLES: sText, sTxtChar,sTxtChar2, MyString Type: String

' Assign String to Convert Character Values
sText = "<![CDATA[ xxxxxxx"
' Determine the Length of the String
iTextLen = Len(sText)
' Clear the Working Output String
MyString = ""

' Let TB show the ASCII Characters for the String
For n = 1 TO iTextLen STEP 1
' Get 1 Character from a String
sTxtChar = mid( sText, n, 1 )
' Convert Character to its ASCII Number
iCharNum = ASCII(sTxtChar)
' Show What is happening on each cycle of the loop
PRINT iCharNum," = ",sTxtChar
' Concatenate the results of the looping changes
MyString = MyString + "Chr(" + AsString(iCharNum)+")+"
Next ' n

' Remove the Last "+" from the created string
iTextLen = Len(MyString) - 1

' Update the created string without the "+" sign
MyString = Left(MyString,iTextLen)

' Show processing Results
PRINT MyString

Results:

The information shown below is the output of create when each character is converted to ASCII, and the text value that number illustrates.

60 = <

33 = !

91 = [

67 = C

68 = D

65 = A

84 = T

65 = A

91 = [

32 =

120 = x

Chr(60)+Chr(33)+Chr(91)+Chr(67)+Chr(68)+Chr(65)+Chr(84)+Chr(65)+Chr(91)+Chr(32)+Chr(120)+Chr(120)+Chr(120)+Chr(120)+Chr(120)+Chr(120)+Chr(120)
