Field help (ALHCODTYP)

This data type is used to specify how the data will be presented.. In the case of a field, the type associated with the field is proposed by default (but can be modified). In the case of an expression, it must be specified (it can be a generic type such as a string of characters A, a local menu M, a short integer C, a date D, a decimal DCB, a long integer L...). In the case of a string of characters, its maximum length will be specified in the Length field that follows ; in the case of a local menu, both the length of the display and the local menu number to be used are specified. If the data type used is linked to an object, it will be possible to use a tunnel to the object management during the enquiry.
