WordPerfect 5.1
Published in Paul W. Ross, The Handbook of Software for Engineers and Scientists, 2018
WordPerfect has the ability to search for and replace text strings. A text string is defined as any sequence of characters. The search and replace feature is an excellent way to search for and replace multiple occurrences of words or phrases without having to be concerned about missing one of the occurrences. To begin the search, press the ALT and F2 keys. The search will begin at the current location of the cursor. When prompted, enter “Y” to replace with confirmation or “N” to replace without confirmation. If replace with confirmation is chosen, WordPerfect will stop at each occurrence of the word for confirmation of replacement. At the prompt, → Srch:, enter the string to be replaced. Press F2 after the string has been entered. DO NOT press ENTER at this point unless the search includes a hard return. Enter the replacement string at the prompt, Replace with:. Press F2. Again, only press the ENTER key if a hard return is to be inserted. The search now begins. If the confirmation option was selected, type “Y” to replace the string or “N” to skip the string each time it is encountered.

A string is an ordered collection of character variables that occupy a contiguous region of memory; that is, a string is basically an array whose elements are all character variables. There are essentially three ways to deal with a string in C++: directly as an array of characters, as a C-style string and using the C++ string class. The array and C-style string approaches are essentially the same except that C-style strings have a null character ∖0 as their last element. The C++ string class provides a simpler way of dealing with strings than the array perspective and, accordingly, we will progress along that route.

The first argument in the , is a regular expression (also known as RegEx or RegExr). Regular expressions are patterns used to match character combinations in a string. Go to these websites (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions, https://regexr.com/) to know more about regular expressions, for creating a new regular expression or for the explanation of a known regular expression. The regular expression used in the code is explained below: – Start of the regular expression – Start of the character set – Matches character – Matches character – End of character set – End of the regular expression – Global Expression flag. It is used to find all the matches (not just the first one).

A symbol is an item. A symbol maybe terminal or nonterminal symbol. Terminal symbols (denoted by lowercase letters, e.g. a) are not rewritable while nonterminal symbols (denoted by uppercase letters, e.g. A) are rewritable. An alphabet (denoted by Σ) is a finite set of symbols. A string is the concatenation of zero or more symbols. A language is a set of strings.
