When I read your code, it is indicated that there are 46 lines of data.
The ascii (text) file has 12 lines (1 header line, 11 lines with dates)
So ..
[a] You included only part of the data
or
[b] the 46 in not what you think its is.
======================================================
The attached script and data produce:
======================================================
(0) nlines=12
(0) international_no=1517
(0) number_of_dataline_str=046
(0) number_of_dataline=46
(0) name=KILO
Variable: date
Type: string
Total Size: 80 bytes
10 values
Number of Dimensions: 1
Dimensions and sizes: [10]
Coordinates:
(0) 15090118
(1) 15090200
(2) 15090206
(3) 15090212
(4) 15090218
(5) 15090300
(6) 15090306
(7) 15090312
(8) 15090318
(9) 15090400
