Commands › DEFINE Command—Define ID Options and Variables › DEFINE VAR—Define Variables Using Existing Variables

Use the following syntax to define new variables using existing variables:

DEFINE VAR newvar = expression

VAR

Requests the definition of a new variable.

newvar

Provides the name of the new variable you want to define.

expression

Assigns any arithmetic expression, the result of which is the value of the new variable. You can use the following to create the expression:

Delimit all variables, operands, and parentheses with blanks. You can use the following operators in the expression:

+ = Addition

- = Subtraction

* = Multiplication

/ = Division

! = Exponentiation

( ) = Parentheses

Examples: The DEFINE Command

The following examples show ways to enter the DEFINE command:

Redefine the length of the ID option TRANID from eight characters to four, starting with position one:
```
DEFINE ID TRANID TRANID(1,4)
```
Redefine the ID option PROGID to use only four characters, starting with position 3:
```
DEFINE ID PROGID PROGID(3,4)
```
Create an ID option named MYKEY with components TRANID and TERMID and places a blank between the two components:
```
DEFINE ID MYKEY TRANID ' ' TERMID
```
Create the variable TRAN %CPUTIME by multiplying TRAN CPUTIME by 100 and then dividing by TRAN LIFETIME:
```
DEFINE VAR TRAN %CPUTIME= ,
 ( TRAN CPUTIME * 100 ) / TRAN LIFETIME
```
The continuation comma allows the command to be continued on a second line.
Create the new variable DCNTMAX that yields the maximum number of transient data sets used by any one transaction:
```
DEFINE VAR TRAN DCNTMAX = TRAN DCOUNT MAX
```
Create the ID option KEY19, which is of record type 19, at offset X'14', of length 8, and of type hexadecimal:
```
DEFINE XID KEY19 PRODUCT=EXPC RECORD=19,
           OFFSET=X14 LENGTH=8 TYPE=HEX
```
The continuation comma allows the command to be continued on a second line.
Create the new variable TERM MYVAR:
```
DEFINE XVAR TERM MYVAR,
      PRODUCT=EXPC RECORD=19 OFFSET=X28,
      LENGTH=2 TYPE=HEX HDR2=myvar
```
The continuation commas allow the command to be continued on subsequent lines.
