 ## 1. Synopsis
+**Output**  
 - `::txtMap::outputMap hexTxt W fileName;`  
   it outputs mapping result
-- `::txtMap::outputHexMap hexTxt W fileName;`  
-  it outputs mapping result in hexadecimals
+- `::txtMap::outputHexMap cMap fileName;`  
+  it outputs hexadecimal map converted from unicode character map
 
-**Parameters**  
+Parameters  
 - `$hexTxt`: utf-8 encoded string that is composed of hexadecimal characters (`0-1` and `a-f`)  
   and newline character (Unicode `U+00000A`)
+- `$cMap`: unicode character map output by `::txtMap::outputMap` or `::txtMap::hexToMap`
 - `$W`: the maximum integer length for output string
 - `$fileName`: name of output file
 
+**Hexadecimal scale**  
+- `scale ?L1 ?R1 ?L2 ?R2????;`  
+  it returns hexadecimal scale
+
+Parameters  
+- `$L1` and `$L2`: optional left characters
+- `$R1` and `$R2`: optional right characters
+
 **Script**  
 - `txtMap.tcl`
