Syntax for Some Object Oriented Programming Language in PeopleSoft

&record.field.Enabled = False is equivalent to UnGray(RecordName.FieldName)
&record.field.Enabled = True is equivalent to Gray(RecordName.FieldName)

in Gray() and UnGray() functions we can not use Variable in place of record name.
Example:
case 1: This will not work
&RECORD = &LEVEL2_ROW.HM_EMP_BEN_D_VW;
Gray(&RECORD.HM_INCURRED_BY);

Case 2: This will work
&RECORD = &LEVEL2_ROW.HM_EMP_BEN_D_VW;
&RECORD.HM_INCURRED_BY.enabled = False;
This is very useful in Row Traversing where we can not use RecordName.FieldName.

&record.field.IsChanged;
