1) CHAIN & ENDCHAIN
this is used to validate many fields. For example, say you have 5 input parameter in a module program. you want to validate these fields.
All the validations are written in a single module. so you can use
Chain.
field <fieldname1>
field <fieldname2>
field <fieldname3>
field <fieldname4>
field <fieldname5>
module check_input
endchain.
The above syntax, will call module check_input for each fieldname.
2) FIELD & MODULE
This will be mostly used where u want to perform different validation.
for example, you have 5 fields. you need to validate these fields indivually in a separte module. Then u can go for this syntax
For example:
field <fieldname1> module check_input1
field <fieldname2> module check_input2
field <fieldname3> module check_input3
field <fieldname4> module check_input4
field <fieldname5> module check_input5
