To pass the parameter, enter the address of the first memory location to be
modified. You will then be prompted for &VALUE1. If you enter, for
example, "0,-1,20, 0ffffh, 4+5*4", the first parameter "0,-1,20," is passed to
&VALUE1 and the remaining parameters "0ffffh," and "4+5*4" are passed to
&ArG_lEfT.
You can also pass the parameters when you invoke the command file (for
example, CMDFILE 1000h 0,-1,20, 0ffffh, 4+5*4).
Other Things to Know About Command Files
You should know the following about using command files:
Command files may contain shell variables. Only those shell variables
1
beginning with "$" followed by an identifier will be supported. An
identifier is a sequence of letters, digits or underscores beginning with
a letter or underscore. The identifier may be enclosed by braces "{ }"
or entered directly following the "$" symbol. Braces are required
when the identifier is followed by a letter, a digit or an underscore that
is not interpreted as part of its name.
For example, assume a directory named /users/softkeys and the shell
variable "S". The value of "S" is "soft". By specifying the directory as
/users/${S}keys the correct result is obtained. However, if you attempt
to specify the directory as /users/$Skeys, the Softkey Interface looks
for the value of the variable "Skeys". This is not the operators
intended result. You may not get the intended result unless Skeys is
already defined to be "softkeys".
You can examine the current values of all shell variables defined in
your environment with the command "env".
Positional shell variables, such as $1, $2, and so on, are not supported.

Neither are special shell variables, such as $@, $*, and so on,
supported.
You can continue command file lines. This is done by avoiding the line
3
feed with a backslash (\). A line terminated by "\" is concatenated
with any following lines until a line that does not contain a backslash is
found. A line constructed in this manner is recognized and executed
as one single command line. If the last line in a command file is
terminated by "\", it appears on the command line but is not executed.
Normally, the line feed is recognized as the command terminator. The
UNIX environment recognizes three quoting characters for shell
commands which are double quotes ("), single quotes ('), and the
backslash symbol (\).
