Routines

AnsiContainsStr	Indicates whether one string is a (case-sensitive) substring of another.
AnsiContainsText	Indicates whether one string is a (case-insensitive) substring of another.
AnsiEndsStr	Indicates whether one string is a (case-sensitive) suffix of another.
AnsiEndsText	Indicates whether one string is a (case-insensitive) suffix of another.
AnsiIndexStr	Provides the index of a specified string in an array of strings.
AnsiIndexText	Provides the index of a specified string in an array of strings.
AnsiLeftStr	Returns the substring of a specified length that appears at the start of a string.
AnsiMatchStr	Indicates whether an array of strings contains an exact match to a specified string.
AnsiMatchText	Indicates whether an array of strings contains a case-insensitive match to a specified string.
AnsiMidStr	Returns the substring of a specified length that appears at a specified position in a string.
AnsiReplaceStr	Replaces all occurrences of a substring within a string, using case-sensitive search.
AnsiReplaceText	Replaces all case-insensitive matches of a substring with another string.
AnsiResemblesText	Indicates whether two strings are similar.
AnsiReverseString	Returns reversed string.
AnsiRightStr	Returns the substring of a specified length that appears at the end of a string.
AnsiStartsStr	Indicates whether one string is a (case-sensitive) prefix of another.
AnsiStartsText	Indicates whether one string is a (case-insensitive) prefix of another.
ContainsStr	Performs a case sensitive search for substring ASubText in string AText. Returns true if one or more instances of ASubText exist in AText.
ContainsText	Performs a case insensitive search for substring ASubText in string AText. Returns true if one or more instances of ASubText exist in AText.
DecodeSoundexInt	Converts an integer representation of a Soundex encoding into the corresponding phonetic string.
DecodeSoundexWord	Converts a Word representation of a Soundex encoding into the corresponding phonetic string.
DupeString	Returns the concatenation of a string with itself a specified number of repeats.
EndsStr	Determines if string AText ends with substring ASubText using a case sensitive string comparison. Returns true if AText ends with ASubText.
EndsText	Determines if string AText ends with substring ASubText using a case insensitive string comparison. Returns true if AText ends with ASubText.
IfThen	Conditionally returns one of two specified values.
IndexStr	IndexStr determines if any of the strings in the array AValues match the string specified by AText using a case sensitive comparison. It returns the zero-based index of the first match in the array, or -1 if no match is found.
IndexText	IndexText determines if any of the strings in the array AValues match the string specified by AText using a case insensitive comparison. It returns the zero-based index of the first match in the array, or -1 if no match is found.
LeftBStr (deprecated)	Returns the substring of a specified number of bytes that appears at the start of a string.
LeftStr	Returns the substring of a specified length that appears at the start of a string.

MatchStr	MatchStr determines if any of the strings in the array AValues match the string specified by AText using a case sensitive comparison. It returns true if at least one of the strings in the array match, or false if none of the strings match.
MatchText	MatchText determines if any of the strings in the array AValues match the string specified by AText using a case insensitive comparison. It returns true if at least one of the strings in the array match, or false if none of the strings match.
MidBStr (deprecated)	Returns the substring of a specified number of bytes that appears at a specified position in a string.
MidStr	Returns the substring of a specified length that appears at a specified position in a string.
PosEx	Returns the index of the first occurrence of a substring within a string.
RandomFrom	Returns a randomly selected element from an array.
ReplaceStr	Replaces all occurrences of a substring within a string, using case-sensitive search.
ReplaceText	ReplaceText replaces all instances of string AFromText to string AToText in the source string AText and returns this value as the result. The replacement is case insensitive.
ResemblesText	ResemblesText uses a Soundex method to determine if string AText and string AOther are similar. The result is True if the two strings a similar according to the Soundex method, and false otherwise.
ReverseString	Returns the reverse of a specified string.
RightBStr (deprecated)	Returns the substring of a specified number of bytes that appears at the end of a string.
RightStr	Returns the substring of a specified length that appears at the end of a string.
SearchBuf	Locates a substring within a text buffer.
Soundex	Converts a string into its Soundex representation.
SoundexCompare	Compares the Soundex representations of two strings.
SoundexInt	Converts a string into an integer that represents its phonetic value.
SoundexProc	Indicates whether two strings are similar.
SoundexSimilar	Indicates whether two strings are similar.
SoundexWord	Converts a string into a Word that represents its phonetic value.
SplitString	Splits a string into different parts delimited by the specified delimiter characters.
StartsStr	Determines whether the substring ASubText begins the string AText using a case sensitive algorithm.
StartsText	StartsText determines if the substring ASubText begins the string AText using a case insensitive algorithm. If ASubText matches the begining of AText, the result is true, otherwise it is false.
StuffString	Inserts a substring into a specified position of a string, replacing the current characters.

Types

TCompareTextProc	TCompareTextProc is a function pointer which specifies a function to compare two string values, AText, and AOther, and return true if these two values are equivilant.
TSoundexIntLength	TSoundexIntLength is the maximum calculation length for the SoundexInt function. The integer value can be from 1 to 8.
TSoundexLength	TSoundexLength is the maximum calculation length of the SoundEx function.
TStringSeachOption	TStringSeachOption is an enumeration that describes the behavior of string searches.
TStringSearchOptions	TStringSearchOptions is set of the enumeration TStringSeachOption.

Variables

AnsiResemblesProc	Controls the algorithm used by AnsiResemblesText to determine when two strings are similar.
ResemblesProc	Controls the algorithm used by AnsiResemblesText to determine when two strings are similar. It is the same as AnsiResemblesProc.
