What is the "ord" function?
Quick search of the help:
HOW CHARACTERS ARE INTERNALLY REPRESENTED
Internally, most computers store characters according to the ASCII format. ASCII stands for American Standard Code for Information Interchange. Characters
are stored according to a numbered sequence, whereby A has a value of 65 decimal, B a value of 66 etc. Several functions which manipulate characters follow.
* CHR
The chr or character position function returns the character associated with the ASCII value being asked, eg,
chr( 65 ) will return the character A
* ORD
The ord or ordinal function returns the ASCII value of a requested character. In essence, it works backwards to the chr function. Ordinal data types are those which have a predefined, known set of values.
Each value which follows in the set is one greater than the previous. Characters and integers are thus ordinal data types.
ord( 'C' ) will return the value 67
* SUCC
The successor function determines the next value or symbol in the set, thus
succ( 'd' ) will return e
* PRED
The predecessor function determines the previous value or symbol in the set, thus
pred( 'd' ) will return c
