Error condition when reading in data lines

The following errors can occur when data lines are read in:

• A procedure line contains data where a command was expected.

• The expression cannot be replaced by a variable or function.

• A procedure line contains a single escape character by itself.

If one of these errors occurs, error handling is normally initiated.

The SET-PROCEDURE-OPTIONS and MODIFY-PROCEDURE-OPTIONS commands provide the DATA-ERROR-HANDLING operand, which can be used to specify that error handling should not be activated (for further details see section “Activation of error handling”).
