It sounds like you can just read this file as text and use contains to look for a Z.

Thank you Rik
I think contains returns a logical value. I want to find his position. My goal is to copy the instructions after the line that contains z.
str = fileread('gcode.txt');
caracter = "Z";
TF = contains(str,caracter)

str = fileread('gcode.txt');
cell_str=strsplit(str,'\n')
character = 'Z';
TF = contains(cell_str,character);
line_num=find(TF);

Maybe the easiest way it to loop through the text line-by-line and check if it contains the character 'Z' using strfind or findstr. Then it should be perfectly straightforward to keep the indices where you find your Zs.
