EVM Mappings

Beside standard C++ functions, there are many handy EVL functions for handling output of the component, strings, decimals, timestamps, etc.

Important: There are several characters when used in an EVD field name which must be handled different way in EVM mapping:

Number at the beginning

When the field name starts with a number then in the mapping must be used prefixed by underscore. E.g. field 01_bill_type would be referenced in mapping as _01_bill_type.

Non-alphanumeric characters

All non-alphanumeric characters in field name have to be referenced in mapping as underscore. E.g. field $bill type (9) would be referenced in mapping as _bill_type__9_.
