ADDRESS TNG Command Syntax

Issue a command from within a REXX program by specifying an ADDRESS TNG statement, as shown:

ADDRESS TNG 'tngcommand operand(s)'

Follow these guidelines when issuing a command:

When specifying a required or optional operand with a command, use parentheses to pass values. For example:
```
PROPERTY(propertyname)
```
Do not name your variables with names reserved for ADDRESS TNG commands when creating REXX programs that issue TNG commands.
Do not include the following characters when creating REXX programs that issue TNG commands,: ()'"<>|. REXX interprets them as REXX delimiters.
Uppercase or lowercase characters are valid. For example, the following are both valid:
```
HOST(hostname) and HOST(HOSTNAME)
```
Leading and trailing blanks are ignored. For example, the following are both valid:
```
HOST(hostname) and HOST ( hostname )
```

Single and double quotes are valid. For example, the following are all valid:

COMMAND(commandstring) and COMMAND('commandstring') and COMMAND("commandstring")
