ERROROFF wvar-names |_ALL_; |
_ALL_
to turn off the error flag for all window variables.
Type: Character
Details |
An error flag can be set either by attributes that are assigned to fields or FRAME entry controls, or by the ERRORON statement.
Use the following statement to clear the error flag for all FRAME entry controls or all fields in the window:
erroroff _all_;
Statements in MAIN do not execute by default if a field is placed in error. Therefore, use a CONTROL statement that specifies the ERROR option to enable ERROROFF to remove the error flag.
The FRAME entry control or field cannot be an element of an array. To remove the error flag for an array element, use FIELD instead.
FRAME entry controls can also use the _erroroff method.
Example |
If a user enters an invalid value in the field TABLENAME, this SAS/AF program resets the value of TABLENAME to the default and turns off the error flag. The field TABLENAME is assigned type INPUT, so the procedure checks to see whether the SAS table exists when a user enters a value for TABLENAME.
INIT: control error; return; MAIN: if (error(tablename)= 1) then do; tablename='my.default'; erroroff tablename; end; return;
