Print ASCII table.
If this function is called without any input argument and without any output argument then prints a nice ASCII-table (excluding special characters with hexcode 0x00 to 0x20). The input argument columns specifies the number of columns and defaults to 4.
If it is called with one output argument then return the ASCII table as
a string without displaying anything. Run demo ascii for examples.
See also: char, isascii, toascii.
The following code
## Display pretty table of conversion between ASCII, decimal and hexadecimal ascii ()
Produces the following output
vtab =
Dec Hex Chr Dec Hex Chr Dec Hex Chr Dec Hex Chr
