Name CharTable
Description Constant data type for a read-only array of chars. These data types are not located in RAM memory saving memory space for other data. Use these data types to store constant data (data which will not change during the whole life of the program). The data types include: ByteTable (store bytes), CharTable (store chars), UCharTable (store unsigned chars), IntTable (store integers), UIntTable (store unsigned ints), LongTable (store longs), ULongTable (store unsigned longs), FloatTable (store floats) and DoubleTable (store doubles).
Syntax 
CharTable var = CharTable(val1, val2, ...);
Methods
count() Returns the number of elements stored in the table
Constructor 
CharTable(data)
Parameters
var unknown datatype variable name referencing the value
valx unknown datatype char chars to store in the table, comma separated
Returns
Example 
// ...
