====== < > Angle Brackets operator ======

 
==== Description ====
 
Use the angle brackets operator ( < > ) to replace data in dynamic string arrays, or to extract data from them.
 
==== Syntax ====
 
//result// = //variable//**<**//field//**>**//
result// = //variable//**<**//field//, //value//**>**//
result// = //variable//**<**//field//, //value//, //subvalue//**>**
 
==== Parameters ====
 
The Angle brackets operator has the following parameters.

^Parameter^Description^
|//Variable//|Designates the dynamic array that contains the data to be extracted or replaced.|
|//field, value,// and //subvalue//|Specifies the location of the data to be extracted or replaced in the dynamic array. //field//, //value//, and //subvalue// may be integer values or any expression that yields integer values.\\ ||

 
==== Remarks ====
 
If the angle bracket syntax appears on the left side of an assignment statement, then a dynamic [[replace|Replace()]] will occur. For example:

 

CUST_REC<3,2> = 'JEFFERSON'

is equivalent to

CUST_REC = Replace( Cust_Rec,3,2,0, 'JEFFERSON')

In this example, the third field, second value is replaced with the string "JEFFERSON". Notice that the 0 (zero) is required in the Replace syntax but not in the angle bracket syntax. Also notice that there is no space between the variable name and the first angle bracket.

Note:  The variable must first be initialized before assigning a value with angle bracket operators.

If the angle bracket syntax is used in any expression to the right of an assignment statement, then an [[extract|Extract]] is implied. Notice that:
 

NAME = REC<4>

is equivalent to

NAME = Extract(REC,4,0,0)
 
==== Example ====
 
<code>
* Extract the third field, Nth value.
INV.DT = MASTER<3,N>

/* Extract the fifth field, Nth value, and subvalue number that is yielded by LINE + 1. */
PROD = MASTER<5,N,LINE + 1>

/* Replace the sixth field, Nth value of MASTER with the second field of PM. */
MASTER<6,N> = PM<2>

* Replace field four of MASTER with "WALL CONSTRUCTION".
MASTER<4> = 'WALL CONSTRUCTION'
