Hello,
there's a lot of code that could be used in / with fields.

Do you mean something like :

fieldname.check()
Syntax:

function long field.check (long has_changed [, long element])

Description


Use this hook to program logical integrity rules for a specified field. The function name is ppmmmvss.bbbb.check(), where pp is the package code, mmm is the module code, vss is the table number, and bbbb is the field name.

Insert a new object Update an existing object
Does the property check for all fields.

The has_changed flag is always set to DAL_NEW. Also for fields that are not changed!
Does the property check for all fields.

The has_changed flag is only set to DAL_UPDATE for changed fields. For unchanged fields, the flag is cleared.



Arguments

long has_changed
[long element ] This is set for array fields only. It indicates the index of the array element that must be checked.


Return values

This hook returns 0 if the value of the field is accepted. It returns a negative value (DALHOOKERROR) if the value is not accepted.

Context

This function can be used in DAL script types.

Property methods

Note
With regards to Extended DAL (DAL2) it is advised to replace this property hook by the new DAL2 Field hooks.

This hook is still supported for backward compatiblity reasons, but the consequence is that the field is not regarded as a DAL2 field.

Example

A property hook programmed in DLL tdsls040:
function extern long tdsls040.oqua.check(long has_changed)
{
if has_changed and tdsls040.stat = tdsls.stat.invoiced then
dal.set.error.message("tdsls44041")
| Order is already invoiced, cannot change
| quantity
return(DALHOOKERROR)
endif
...
return(0)
}
