using the "readline" function to read a specific line

i am trying to write code to assign values from a line of a text file to variables in my program. the problem is that I don't need all the values written in the text file assigned to variables. So. Basically I want to know if there is a way to use "ReadLine" to access specific lines in a text file.

any type of help would be appreciated

re: using the "readline" function to read a specific line

So you're saying you only need lines 10, 15, and 21 for example?
Read all the lines into an array, then use array elements 9, 14 and 20
