Intel® Fortran Compiler 18.0 Developer Guide and Reference
The NEWUNIT specifier opens a file on an unused unit number that is automatically chosen. It also returns the unit number that was chosen. It takes the following form:
NEWUNIT = u-var
u-var |
Is a scalar integer variable that is assigned the automatically chosen unit number. It is always a negative integer. |
If the OPEN is successful, u-var can be used in subsequent I/O statements to access the connected file.
If an error occurs during execution of the OPEN statement containing the NEWUNIT= speciifier, the processor does not change the value of the variable.
