ADDRESS PPQ Command Syntax

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

ADDRESS PPQ 'ppqcommand operand(s)'

Follow these guidelines when issuing a PPQ command:

When specifying a required or optional operand with a PPQ command, use parentheses to pass values. For example:
```
COUNT(numitems)
```
Uppercase or lowercase characters are valid. For example:
```
QUEUE(QUE_1) 
queue(que_1)
```
Leading and trailing blanks are ignored. For example:
```
ITEM(item) 
ITEM ( item )
```

Single and double quotes are supported. For example:

CMDRESP(destination) 
CMDRESP('destination') 
CMDRESP("destination")

When creating REXX programs that issue PPQ commands, do not name your variables with names reserved for PPQ commands. Also, do not include the following characters: ( ) ' " < > |, as they are interpreted by the REXX interpreter as REXX delimiters.
Operands shown in brackets ([ ]) are optional.
