The Data Environment for ADELIA Programs

The Question/Answer programming interface checks the instructions against a work context that is permanently attached to each program.

This work context forms the data environment.

The following information is held In the data environment:

• All the fields that belong to the files specified in the data flow phase ("Views").

• The fields in the screen or report layout.

• Any work fields specific to the program.

Lists

Variables

List of all the variables in the current program, organized in groups according to their origin.

The following details are given for each variable:

• • DDS code,

  • name (or guide word),

  • length,

  • number of decimal places,

  • dimensions 1 and 2 with arrays,

  • origin.

By scrolling horizontally, you may also see the layout name, the reference field, the renamed name and the array dimension (version 4 of Adelia for AS/400).

The list is first sorted by alphabetical order of origin, then by layout name, then, within each origin group, by alphabetical order of name (guide words).

With work variables the origin will be left blank.

With file fields the file name will be given.

With screen and report layout fields the values "WORKSTN" or "PRINTER" will be given.

Only work variables can be created, modified or deleted.

You can, however, modify the guide word or name of file fields by clicking on the Rename button.

Layout fields are available for consultation only.

Multiple selection list.
