It stores the floating point numbers, such as 2.0, 3.1415, -100.876, etc. Character strings are considered to be "internal files" in fortran. If you want to replace all spaces, use replace replace ('NES 123_4_5', ' ', '') If you only want to replace the space after the first three characters, you can use regexp_replace regexp_replace ('NES 123_4_5', ' (^ [A-Z] {3}) ( )', '\1') The regular expression will look for there (uppercase) characters at the beginning.
