How do you write a VI that changes letters in a string?

[iam_daiana]

I need to write a programm that changes every letter in a string with the next letter in the alphabet. ('a' changes to 'b' and so on) Can anyone help? (Labview 14.0)

z becomes a ?

Same for capitals ?

Numbers and other signs remain unchanged ? 

[iam_daiana]

yes, z become a, same for capitals and there are no numbers and symbols in the text file.

Convert the letter to ascii code, add 1 than convert back to letter

Hi daiana,

convert the string to an U8 array and add 1. Then convert back to string…

yes, z become a, same for capitals and there are no numbers and symbols in the text file.

This becomes a different problem. Now I would use a lookup table (but still work with conversion to U8 array).

Check if the number is greater than "z" code then change the number to the ascii number equivalnt to a

Use String To Byte Array to make an array of characters.  Then use a FOR loop (autoindexing) to do the conversion.  You will want a case structure to handle the z cases differently from the default and leave punctuation alone.  Autoindex the results out of the loop and then use Byte Array To String.

This will work with any characters in the text.

PS : Am I to generous by providing a code ?

Congratulations crossrulz for being faster !
