to replace the text in the file of a notepad

[ilya1111]

int G1 G2 ={any text}

I just replaced int to str. Does it have to be int and not str?
if G1 and G2 values are always different, how the macro gets these values?

I think it can be done by lines, to cut second line and pust it in first line. words "bom" and "bibom" constant words
