Intel® Fortran Compiler 17.0 Developer Guide and Reference
Statement: Positions a direct access file at a particular record and sets the associated variable of the file to that record number. It is comparable to a direct access READ statement with no I/O list, and it can open an existing file. No data transfer takes place.
FIND ([UNIT=] io-unit, REC= r[, ERR= label] [, IOSTAT= i-var])
FIND (io-unit 'r [, ERR=label] [, IOSTAT=i-var])
io-unit |
Is a logical unit number. It must refer to a relative organization file (see Unit Specifier). |
r |
Is the direct access record number. It cannot be less than one or greater than the number of records defined for the file (see Record Specifier). |
label |
Is the label of the executable statement that receives control if an error occurs. |
i-var |
Is a scalar integer variable that is defined as a positive integer if an error occurs, and as zero if no error occurs (see I/O Status Specifier). |
In the following example, the FIND statement positions logical unit 1 at the first record in the file. The file's associated variable is set to one:
FIND(1, REC=1)
In the following example, the FIND statement positions the file at the record identified by the content of INDX. The file's associated variable is set to the value of INDX:
FIND(4, REC=INDX)
