Variable validation z/OS ISPF Dialog Tag Language Guide and Reference SC19-3620-00 |
|
DTL allows you to define translate lists and validity checks as part of the variable class definition by using tags nested within the VARCLASS tag. These built-in translations and checks are especially useful because ISPF automatically performs them on variable values, so the dialog application does not need to. Note: Translations and checks are performed only on variable values
that are intended for display. For instance, before displaying the
data from a variable specified on the DATAVAR attribute of a DTAFLD
tag, ISPF performs any specified translations on the variable retrieved
from the application to construct the correct display value. However,
ISPF does not perform translations on a variable specified as the
CHECKVAR attribute of a CHOICE tag.
