Discussion
The ENVIRONMENT statement describes a temporary environment field to be created in a report.
Environment fields are used to obtain data from the system environment. They are temporary fields that are not found in the repository. You must specify the field’s name, data type, and size. The maximum number of environment fields that can be defined in a report is 99.
If the temporary environment field does not have a unique name, it must be preceded by “TEMP.”. For example, if the temporary field is called SYSTEM and one of the selected files also contains a field called SYSTEM, you would specify the temporary field like this:
TEMP.SYSTEM
Examples
- In the example below, ENVIRON1 is the name of the field, and its size is 30. It is an alphanumeric field.
ENVIRONMENT ENVIRON1 TYPE ALPHANUMERIC SIZE 30
- In the following example, ENVIRON2 is the name of the field and its size is 6. It is a date field with the storage format YYMMDD. The format in which the field will be displayed is “MM/DD/YY.” The associated user text string is “Start Date.”
ENVIRONMENT ENVIRON2 TYPE DATE SIZE 6 FORMAT "MM/DD/YY" USERTEXT "Start Date" STORED YYMMDD
