don't understand the unix script

if {"$my_ext_type" = MAIN]; then
cd $v_sc_dir
Filex.SH $v_so_dir\/$v_fr_file
Can somebody tell me what does this suggest. I am pretty new to unix and
I am getting confused.
What i understood from here is
If we have a file extension name as MAIN
which we have then we change the directory to the path in
$v_sc_dir. And there we find the file Filex.SH [which we have].
Now comes the problem of my understanding. We have this path
$v_so_dir. But i dont know what this |[back slash means] can somebody tell me.
Also we have $v_fr_file -spool file. I am pretty confused. Please help me.

In bash '\' (backslash) is used for escaping special characters (for example spaces in file names). However I don't know why it's necessary to escape '/' in this case.
