Using a Custom Block in combination with an algorithm, one can quickly check if a particular string passed in as an argument has a list of characters within it.
Programming
The following script can be used to check the condition. The variable (condition) is evaluated to true or false depending on if the string has the particular characters. For this script, assume the following:
(condition)is used to determine true or false (the return variable)(i)is a variable used for iterating (moving from one character to another)(matches)is a variable used to determine the number of characters detected in the base string(allLetters:: list)is a list compiled of the characters being checked for; it is useful because lists have a built-in function for checking contained items
 Note: | This is different than Checking if a String Contains a String because this script does not require the characters to be in sequential order. |
define check if (base) has (characters)
set [condition v] to [false]
delete all of [allLetters v]
set [i v] to (1)
repeat (length of (characters)) //adds each letter to a list
add (letter (i) of (characters)) to [allLetters v]
change [i v] by (1)
end
set [i v] to (1)
set [matches v] to (0)
repeat (length of (base))
if <[allLetters v] contains (letter (i) of (base))> then
change [matches v] by (1)
end
change [i v] by (1)
end
if <(matches) = (length of [allLetters v])> then
set [condition v] to [true]
end
