Statement Syntax
4, the selected operand is 25. Parentheses are not required in a SET
statement.
CHANGE NFORM TO X OF
"FORMA", "FORMB", "FORMC",
OPSELECT
X may be a value between 1 and 4. If its value is 4, the field name
OPSELECT is chosen. The value of OPSELECT must be type character to
conform to the other elements in the list, and to make sense it should
contain a form name. No parentheses are needed in a CHANGE statement.
If an index has a value beyond the number of elements in the list or is $EMPTY, an error is
returned.
