C --FFVRNG parses a range of reals. A range has one of the following
|
||
|
|
C --forms:
|
||
|
|
C -- r1 assume r2 = r1, r3 = 0.
|
||
|
|
C -- r1 TO r2 assume r3 = 0.
|
||
|
|
C -- r1 TO r2 STEP r3
|
||
|
|
C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- IFLD - IN/OUT - the index of the current field number, incremented
|
||
|
|
C -- INTYP - IN - the input type array from the free-field reader
|
||
|
|
C -- CFIELD - IN - the input string array from the free-field reader
|
||
|
|
C -- RFIELD - IN - the input integer array from the free-field reader
|
||
|
|
C -- EXPECT - IN - the type of range being parsed, for error
|
||
|
|
C -- RMAX - IN - the maximum range value
|
||
|
|
C -- RANGE - OUT - the input range value array:
|
||
|
|
C -- (1) = r1, (2) = r2, (3) = r3;
|
||
|
|
C -- partially set on error
|
||
|
|
C -- * - return statement if the range is invalid; message is printed
