VFEVALERR

 NUMBER:  68

 ERROR CODE:  F

 MESSAGE TEXT:  variable format expression value error

 EXPLANATION:  The value of a variable format expression was not
 within the range acceptable for its intended use; for example, a
 field width was less than or equal to zero.  A value of one was
 assumed, except for a P edit descriptor, for which a value of zero
 was assumed.

 The ERR transfer is taken after completion of the I/O statement for
 this error number.  The resulting file status and record position
 are the same as if no error had occurred.  However, other I/O
 errors take the ERR transfer as soon as the error is detected, so
 file states and record position are undefined.
