Watch Window

As you debug, the Watch window displays the values of variables and expressions.

To display the window, click Debug > Windows > Watch > Watch n while debugging.

Use the Watch window to:

• View the value of variables using one of these methods to add a variable to the Watch window:
  • Right-click a variable in the editor and click Add Watch.
  • In the Watch window, click an empty row in the Name column, and type a variable.
• View the value of expressions by clicking an empty row in the Name column, and typing an expression.

  The supported expressions are: normal numeric arithmetic expression with intrinsic functions and the single use of alphanumeric intrinsic functions. For example, if you have the following variables defined:

  01 a pic 999 value 2. 
  01 b pic xxxx comp-x value 3. 
  01 xyz value "abc". 

  You can use expressions of the type:

  a + b * 1
  a + function max(10,20)
  function upper-case(xyz)
  1 + 10
  function hex-of(b)

  The following expressions are not supported - logical operators such as b-and and b-or; ISO2002 user defined methods; inline method invokes, and intrinsic functions which are evaluated at compile time.

• Change the display format for all values from decimal to hexadecimal by right-clicking in the Watch window, and then clicking Hexadecimal Display.
• Change the display format of values on an individual row:
  1. Select a row.
  2. Press F2.
  3. Type a modifier after the name of the variable or the expression as follows:

     h or x

     Type Variable,h or Variable,x to always display the variable or the expression in hexadecimal format.

     d

     Type Variable,d to always display numeric variables in decimal format and strings - as text.
