I have two files
File1 has trailer as below
TR|2|120
File2 has trailer as below
TR|1|100

it should add both the fields from trailer of file 1 and 2....so that file2 has a trailer as
TR|3|220

I have a variable
var=string1:string2:string3

I want to get the string de-concatenated and put it as
var1=string1
var2=string2
var3=string3

Thanks in advance.
