Because you did not pass the array A1 into it, you passed the string "A1" into it. Variables do not work that way.

Yeah..I agree its string..any alternate solution ???

My general suggestion would be "don't do that"... Almost no language allows this, and it's still ugly in those which can. It's simple to organize your data in any linear structure so it's unnecessary, too.

The usual alternative for these is arrays, especially associative arrays or multidimensional arrays instead of variable variable names, not as well as. A[0,...] instead of A0[...] essentially.
