Control File: line cannot start with ':' or '='

A control file can only include fields and variables. Although a field can be continuated, which means a line can start with a space or a tab, any other line must start with a valid name before the colon (:) as used for fields or the equal (=) as used for variables.

This error is generated if the field or variable name is missing on a line.

VALIDField: Value
Variable= Value

INVALID: Value
= Value
