FILE SWITCHES

FILE SWITCHES (SET)

Set Subcommand

Probe for values pertaining to Dataplot file names, unit numbers, and file status values.

Dataplot utilizes a number of files. In some cases, these files are previously created file names (e.g., the Dataplot help files, the file containing the sign-on message). In other cases, these files are dynamically named during a Dataplot session (e.g., the files associated with READ, WRITE, or CALL commands).

In addition to the file name, there is also a Fortran unit number associated with that file. Fortran unit numbers are typically between 1 and 99 (for Dataplot files, they typically are greater than or equal to 10). Files also have a status value. A status value of OLD is used for files that are expected to already exist (and are not modified by the user during a Dataplot session). This would include the help files, the file containing the sign-on message, and several others. A status value of UNKNOWN is used for files that can be modifed during a Dataplot session and that may not currently exist. An example would be the file associated with the READ command.

Unit numbers are typically not changed and the file status is determined dynamically. So these would typically only be used by the PROBE command (i.e., not by SET). The SET command can be used to change the name of the plot files (IPL1NA, IPL2NA). The SET command would not typically be used to change the name of the other files listed below.

These setting are typically of interest to the Dataplot developers for debugging purposes. However, they can be used by any Dataplot user.

The list of available file name and unit number switches is

INEWNA	-	the name of the news file
IMAINU	-	the Fortran unit number for the mail file
IMAIST	-	the current status of the mail file
IMAINA	-	the name of the mail file Note: the mail file is obsolete and these values are no longer set.
IHELNU	-	the Fortran unit number for the help file
IHELST	-	the current status of the help file
IHELNA	-	the name of the help file
