 EASI>SOURCE = "text"           | single line model to use directly

UNDEFVAL

Optionally specifies the value that should be used for the result of numeric expressions which contain an undefined operation (such as division by zero or the logarithm of a negative value).

 EASI>UNDEFVAL=n                | use n for result of expression
 EASI>UNDEFVAL=                 | if any undefined operations are
                                | encountered, abort model
