Abbreviating Command Lines
• Abbreviating File Specifications with Percent Wildcards
You can use the percent (%) wildcard to substitute for a single character in the
input file name or file type. For example, the following command displays all the
files on the system device that have a two-letter file name that begins with a D
and have a MAC file type:
.DIR SY:D%.MAC
Note that the % wildcard is not valid in output file specifications, though the *
wildcard by itself (with no file specification) is valid as an output specification.
For further information on using wildcards, see the description of the command
you want to use. See also the SET WILD command.
Substituting Symbols for Command Strings
The LET utility enables you to substitute single characters for a command string.
KMON then translates that character as the command string. However, every time
you type that substitution character, you no longer get that character; rather, you
get the command for which it stands.
To substitute symbols for commands, see the LET utility description in the RT–11
System Utilities Manual and the SET SL command description in this manual.
