TERMINAL INPUT/OUTPUT LOGICAL UNIT

Syntax:

[NO] TERMINAL INPUT [LOGICAL] UNIT <integer> [NO] TERMINAL OUTPUT [LOGICAL] UNIT <integer>

These commands specify the logical unit numbers used for terminal input and output. The specifications are used by fpt:

to control conversion of ISAM file accesses to sub-program calls. It is assumed that ISAM files can not be opened on the terminal logical unit numbers. Please see the command CHANGE ISAM FILE ACCESSES TO SUB-PROGRAM CALLS for a description of this process;
to specify the logical units affected by the command COMMENT OUT OPEN OF THE TERMINAL.

Where to Use this Command

Operating system command line	Yes
Configuration file, config.fsp	Yes
Specification (fsp) files, *.fsp	Yes
Interactively, to FPT> prompt	Yes
Interactive command files	Yes
Embedded in the Fortran code	Yes

Default

By default, unit 5 is assumed to be used for terminal input and unit 6 for terminal output. Note that defaults may be changed in the configuration file.

Example

To specify the use of logical units in a program in an fsp file:

% indexed units 14 15 16 17 % non-indexed units 1 2 3 4 8 9 % terminal input unit 5 % terminal output unit 6
