PCA Command
Defines a command synonym by associating a symbol name with a
list of one or more PCA commands.
Format
DEFINE/COMMAND symbol-name = "command-string"
1 – Parameters
symbol-name
Specifies the symbol name that you want associated with a list
of PCA commands. The symbol name can be up to 255 characters long
and may include letters, digits, underscores, and dollar signs.
It cannot start with a digit. If symbol-name is already defined,
the new definition replaces the old definition.
command-string
Specifies the string of PCA commands to associate with the symbol
name. The command string must be enclosed in quotation marks and
consist of the first part of a PCA command, a whole command, or a
list of commands separated by semicolons
2 – Description
The DEFINE/COMMAND command associates a symbol name with a PCA
command string. The command string consists of one or more PCA
commands separated by semicolons, and must end with a partial or
full PCA command. When the symbol name appears at the start of a
subsequent PCA command, it is replaced by the command string. The
resulting string is parsed and executed by PCA. DEFINE/COMMAND
thus gives you the same command abbreviation capability as the
symbol assignment statement (symbol-name := command-string) in
DCL. The command string may contain previously defined commands,
when those symbols translate directly into PCA commands. (PCA
supports one level of symbol translation.)
To display the current symbol definitions created by
DEFINE/COMMAND, use the SHOW SYMBOL/DEFINED command.
3 – Examples
PCAC> DEFINE/COMMAND SA = "SHOW ALL"
PCAC> SA
This command associates the symbol SA with the PCA command
SHOW ALL. When the SA command is used, SA is expanded to the
equivalent command string, which PCA then executes.
