To increase flexibility of command files by using
&ArG_lEfT
1 Use the special parameter &ArG_lEfT anywhere in the command file.
2 Pass zero or more arguments to the command file on the command line.
You can create highly flexible command files using the special parameter
&ArG_lEfT. It must be entered with the preceding ampersand (&) and exactly in
the combination of upper and lower case letters shown here. It is not a parameter in
the sense of command file formal and actual parameters. (See “To pass parameters
to a command file” for more information.) Instead, it is a special parameter that
may be included in either a command file with formal parameters or in a command
file without formal parameters.
When the interface finds &ArG_lEfT in a command file, it replaces it with the
union of all arguments remaining in the string of arguments passed to the command
file. Arguments for this special parameter must be passed on the command line and
can be zero or more in number. The interface will not prompt for a value for
&ArG_lEfT. If you do not pass any values, the interface removes the special
parameter and executes the command associated with the special parameter without
any arguments.
Example
The following three commands are all variations of the display memory command:
display memory
display memory 1000h
display memory 1000h, 2000h thru +20h, 3000h
The first command displays memory in the format specified by the last memory
display command. The second command displays memory at address 1000h in
blocked word format. The third command displays memory at two specific memory
locations and also from a range of locations all in a single blocked word display.
