Parameters
x is an expression whose value is a non-negative integer.
Examples
HIGH(3) /* Returns a character string whose length
is equal to 3 characters and in which
each character is hexadecimal 7F. */
Description
The HIGH function returns a character string of length x, in which each character is the highest character in the collating sequence (ASCII = hex 7F).
The HIGH function uses a 256-byte collating string.
The value of x must be non-negative. If x = 0, the result is the null character string.
