The form named Information is comprised of two sections; Part1 and Part2. Part1 has these fields: abc1, abc2, and abc3. Part2 has these fields: abc3 and abc4.
The form named Multi-section is comprised of three sections: Section1, Section2, and Section3. Section1 has objects with these field names: a/n, date, yes/no, and multiline.
Section2 has the same objects with the same field names as Section1.
Section3 has following objects: graphic, box, and input value.
The DAL script which is executed is on a field named Test on Part1 of Information.
Here are some examples:

Procedure |
Result |
Explanation |

Return(DelField ( "abc3" )); |
1 |
Abc3 on Information/Part1 is deleted because the section, field, and group parameters were omitted specified. The system defaulted to the current section, form, and group. |
|
Return(DelField ( "abc3", "part2" )); |
1 |
Abc3 on Information/Part2 is deleted because you specified Part2 and the form defaulted to the current form, Information. Note that Abc3 will still exist on Information/Part1. |
|
Return(DelField ( "test" )); |
0 |
Test is not deleted because it is the current field. |
|
Return(DelField ( "a/n" )); |
0 |
The field a/n is not deleted because it is not on Information/Part1. |
|
Return(DelField ( "a/n", "Section1" )); |
0 |
The field a/n is not deleted because Section1 is not a field on the current form (Information). |
|
Return(DelField ( "a/n", "Section1", "Multi-section" )); |
1 |
The field a/n on Multi-section/Section1 is deleted because this field is on the specified form/section. |
|
Return(DelField ( "a/n", , "Multi-section" )); |
1 |
The field a/n on Multi-section/Section1 is deleted because field is on the specified form and the section parameter defaults to the first section on the form. Field a/n on Multi-section/Section1 will still exist. If you immediately execute the script again, the field a/n on Image2 would be deleted. |
|
Return( DelField ( "a/n", , , "DAL Test Company" )); |
1 |
The field a/n on Multi-section/Section1 is deleted because it was is the first field in the group, DAL Test Company. Field a/n on Multi-section/Section2 will still exist. If you immediately execute the script again, the field a/n on Image2 would be deleted. |
|
Return(DelField ( "box", "Section3", "Multi-section" )); |
