C --Parameters:
|

C -- IFLD - IN/OUT - the index of the current field number, incremented
|

|
|
C -- INTYP - IN - the input types from the free-field reader
|

|
|
C -- IFIELD - IN - the integer fields
|

C -- EXPECT - IN - the value to expect string, for error
|

C -- IDEFVL - IN - the default value if field is empty
|
||
|
|
C -- IVAL - OUT - the integer value, set only if no error
