ordinary character

Ordinary characters consist of all those printed and non-printed characters that are not explicitly designated as metacharacters. This includes all upper-case and lower-case alphabetic characters, all numbers, all punctuation marks, and some symbols.

The simplest regular expression is a single ordinary character that matches itself in the string being searched. For example, the single-character pattern 'A' can match the letter 'A' anywhere in the searched string. Here are some examples of single-character regular expression patterns:

/a//7//M/

The equivalent VBScript single-character regular expression is:

"a""7""M"

Multiple single characters can be combined to make a larger expression. For example, the following Visual Basic Scripting Edition regular expression is nothing but an expression created by combining the single-character expressions 'a','7'and' M'.

/a7M/

The equivalent VBScript expression is:

"a7M"

Notice that there are no concatenation operators. All you have to do is put one character after another.
