Re^2: Pattern matching

Sorry i might forget to mention that the line MODULE C17 (N1, N2, N3, N6, N7, N22, N23) is actually obtained from a text file.

MODULE C17 (N1, N2, N3, N6, N7, N22, N23);
INPUT N1, N2, N3, N6, N7;
OUTPUT N22, N23;
WIRE N10, N11, N16, N19;
NAND NAND2_1 (N10, N1, N3);
NAND NAND2_2 (N11, N3, N6);
NAND NAND2_3 (N16, N2, N11);
NAND NAND2_4 (N19, N11, N7);
NAND NAND2_5 (N22, N10, N16);
NAND NAND2_6 (N23, N16, N19);
ENDMODULE

I tried your coding but it also prints the NAND line.

Unfortunately, what you have provided now is still not a complete spec. You might want any of these things: Just process the first line of the file. Just process the first line which has a bracket. Process every line which starts with an M. Process every line which starts with an M and contains a bracket. ... So, your first task is to create a tight specification. After that you can devise an algorithm and only then start to consider the coding.	[reply]
