Reclassify by ASCII

I want to reclassify the landuse map as follows:

Original code	Field	New code to be given
0100	Rice paddy	1
0200	Agricultural fields	2
0500	Forest	3
0600	Barren area – OTHERS	4
0700	Built up area	5
0901	Road	5
0902	Railway	5
1000	Other inland type	4
1100	Inland waters	6
1400	Coastal area	4
1500	Ocean	7
1600	Golf course	4
0000	Outside areas	4

So I made an input ASCII remap files as follows:

# Remap Table for cell value reclassification
0100 : 1
0200 : 2
0500 : 3
0600 : 4
0700 : 5
0901 : 5
0902 : 5
1000 : 4
1100 : 6
1400 : 4
1500 : 7
1600 : 4
0000 : 4

The output that I wanted was the reclassified map with 7 unique values. I wanted codes like 0700, 0901 and 0902 to be merged together and given the value 5. However, my reclassified map looks like this.

When I open the symbology window, I do not have the option of seeing the map by different attributes.

When I do the reclassification manually, I get results like this.

What is wrong with my ASCII file?

I suspect 0100 etc are not numeric ...

Each assignment line maps a value or range of values from the input raster to an output value. Only numeric values are accepted on an assignment line.

Thank you! I changed the characters from strings to short integers and it worked!
