you could delete the $ and put just the parameter 'source'

a = load 'source' using PigStorage();
store a into 'target' using PigStorage();

you just need to pass parameter before executing your pig script because right now you are passing parameter after your pig execute command. you can pass your parameter like -

pig -param parameter=<parameter value> /home/user/unbz2.pig
