The R command places an executable system program in memory and starts
@R (PROGRAM) filespec /switch
filespec is the file specification of any executable
Default dev:<directory> - SYS:
Default .typ - .EXE
/switch is /USE-SECTION:n
specifies the memory section (from 0 to 37
octal) in which your program is to run. You
can use this switch only if your program can
be contained in one section.
Need for R Command
Although in most cases you can run system programs by simply
typing the program name in place of an EXEC command, the R
command is necessary for running a program whose name is the
same as an EXEC command or an abbreviation for an EXEC
command. For example, if your site has a system program
named CONNECT, it must be run with the R command in order to
distinguish it from the EXEC's CONNECT command. If you have
a system program named GE, it must be run with the R command
to distinguish it from the GE abbreviation for the GET
Cancels the Ephemeral Attribute
If a system program has been set ephemeral by the system
manager or, you have given a SET PROGRAM EPHEMERAL command,
you can cancel the ephemeral attribute by running the
program with the R command instead of typing the program
name as an EXEC command.
For more information on the ephemeral attribute, see the
ERUN help file.
If you redefine logical name SYS: to be different from the
system-wide definition, you should include SYS: in the
search list if you want to use the R command to run system
programs. For further information, see the section titled
Redefining System Logical Names in the DEFINE help file.
Effect on Memory
The R command clears any unkept forks, places in memory and
starts the specified program.
