How to initialize a large buffer by quartus prime

Hi, I want to init my written RAM by a mif file.

Here is my mif file:

DEPTH = 256;
WIDTH = 32;
ADDRESS_RADIX = HEX;
DATA_RADIX = HEX;

CONTENT
BEGIN
00 : 0000 0000;
01 : 0000 0000;
02 : 0000 0000;
03 : 0000 0000;
04 : 0000 0000;
05 : 0000 0000;

.

.

.

FF : 0000 0000;

END;

And here is the error from the quartus prime:

Error (10852): Verilog HDL error at DPbuffer_init.mif(1): illegal character 'p' in hexadecimal number

Error (10170): Verilog HDL syntax error at DPbuffer_init.mif(1) near text: p. Check for and fix any syntax errors that appear immediately before or at the specified keyword. The Intel FPGA Knowledge Database contains many articles with specific details on how to resolve this error. Visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number.

Error (12152): Can't elaborate user hierarchy "soc_system:soc_inst|m_buffer:dpbuffer_0"

Do you guys know how to fix that or is there another way to init the RAM?

Thank you.
