看你输出的是否是推进型，默认是yes，这句话就可以省掉，就是推进型，你在写完之后，指针就定位在记录尾部；如果是NO，那么就允许写一部分，指针定位于你这这部分的最后一个字符后面。以后还可以接着的。

Advance Specifier
The advance specifier determines whether nonadvancing I/O occurs for a data transfer statement. It takes the following form:
ADVANCE=c-expr
c-expr
Is a scalar character expression that evaluates to 'YES' for advancing I/O or 'NO' for nonadvancing I/O. The default value is 'YES'.
Trailing blanks in the expression are ignored.
The ADVANCE specifier can appear only in a formatted, sequential data transfer statement that specifies an external unit. It must not be specified for list-directed or namelist data transfer.
Advancing I/O always positions a file at the end of a record, unless an error condition occurs. Nonadvancing I/O can position a file at a character position within the current record.
