IDL_String

• CapWords - Capitalize any words contained within the string.
• CharAt - Returns the character at the supplied index.
• Compress - Removes all white space.
• Contains - Returns true if the string contains a given substring.
• EndsWith - Returns true if the string ends with the given string.
• Extract - Returns part of the string using a regular expression.
• IndexOf - Returns the index of a character or substring.
• Insert - Inserts another string.
• Join - Combines multiple strings into a single string.
• LastIndexOf - Returns the last index of a character or substring.
• Matches - Returns true if the string matches a regular expression.
• Remove - Remove part of a string.
• Replace - Replaces text within the string.
• Reverse - Reverse a string.
• Split - Split into substrings using a regular expression.
• StartsWith - Returns true if the string starts with the given string.

• Trim - Removes leading and trailing white space.

IDL_Variable

• Compare - Compare to another variable and return –1, 0, or 1 for each value.
• Convert - Convert the variable to a different data type.
• Diff - Returns the unique elements that have been added to or removed from a variable.
• Equals - Tests whether two variables are equal.
• Filter - Returns only data values that successfully pass through a user-defined filter or Lambda function.
• Finite - Returns only the finite values within an array.
• FromBits - Converts the variable from an array of bits.
• Hashcode - Returns a hash code for the variable.
• HasValue - Returns 1 (true) if the variable contains a given set of values.
• IsFinite - Returns 1 (true) if all of the values in the variable are finite.
• IsInfinite - Returns 1 (true) if all of the values in the variable are infinite.
• IsNaN - Returns 1 (true) if all of the values in the variable are NaN.
• IsReal - Returns 1 (true) if the variable is not a complex data type.
• Map - Pass all data values through a user-defined function or Lambda function.
• NestedMap - Use a nested loop to pass the data values and arguments through a user function.
• PtrValid - Returns the validity of its pointer arguments, or alternatively returns a vector of pointers to all the existing valid pointer heap variables.
• Reduce - Use a user-defined function or Lambda function to cumulatively combine all values from left to right and return a single value.
• Reform - Change the array dimensions.
