LEN_TRIM: Trimmed length of a character string or of an array (f)

• • trimmed_length_of_string = LEN_TRIM(string) ! length of string without counting trailing blanks
  examples:
  • • CHARACTER str*100/"abc"/
    • trimmed_length_of_str = LEN_TRIM(str) ! 3
  • • len_hello = LEN_TRIM("hello ") ! = 5
• • trimmed_length_of_array = LEN_TRIM(array) ! length of array without counting trailing zeros
  examples:
  • • DIMENSION vector(10), matrix(3,4)
    • vector = 0 ! set all elements to 0
    • trimmed_length_of_vector = LEN_TRIM(vector) ! 0
  • • vector = (101,102,103) ! assignment to the first 3 elements
    • trimmed_length_of_vector = LEN_TRIM(vector) ! 3
  • • matrix = $ ! assign 1, 2, .. 12 to matrix
    • trimmed_length_of_matrix = LEN_TRIM(matrix) ! 12
  • • len_hello = LEN_TRIM("hello ") ! = 5
