Hi, tarkyss
Does the text file read contains other data except for the binary or heximal data?
Verilog only provides $readmemb and $readmemh system tasks, which can not read string types and other types supported by C and VHDL.

verilog read text file

make sure u have the file a.txt in the right directory . It should be in the directory from where u run ur simulations not where the verilog file might have been kept. Check that
