The CARRIAGECONTROL specifier indicates the type of carriage control used when a file is displayed at a terminal. It takes the following form:
CARRIAGECONTROL = cc
Is a scalar default character expression that evaluates to one of the following values:
'FORTRAN' |
Indicates normal Fortran interpretation of the first character. |
'LIST' |
Indicates one line feed between records. |
'NONE' |
Indicates no carriage control processing. |
The default for binary (W*32, W*64) and unformatted files is 'NONE'. The default for formatted files is 'LIST'. However, if you specify compiler option vms or fpscomp general, and the unit is connected to a terminal, the default is 'FORTRAN'.
On output, if a file was opened with CARRIAGECONTROL='FORTRAN' in effect or the file was processed by the fortpr format utility, the first character of a record transmitted to a line printer or terminal is typically a character that is not printed, but is used to control vertical spacing.
