4.5.3 Evaluating Expressions
  To evaluate a language expression, use the EVALUATE
  command as follows:
  DBG> EVALUATE lang_exp

  The debugger recognizes the operators and expression syn-
  tax of the currently set language. In the following example,
  the value 45 is assigned to the integer variable WIDTH; the
  EVALUATE command then obtains the sum of the current
  value of WIDTH plus 7:
  DBG> DEPOSIT WIDTH = 45
  DBG> EVALUATE WIDTH + 7
  52
  DBG>

  Following is an example of how the EVALUATE and the
  EXAMINE commands are similar. When the expression fol-
  lowing the command is a variable name, the value reported
  by the debugger is the same for either command.
  DBG> DEPOSIT WIDTH = 45
  DBG> EVALUATE WIDTH
  45
  DBG> EXAMINE WIDTH
  SIZE\WIDTH: 45

  Following is an example of how the EVALUATE and
  EXAMINE commands are different:
  DBG> EVALUATE WIDTH + 7
  52
  DBG> EXAMINE WIDTH + 7
  SIZE\WIDTH: 131584

  With the EVALUATE command, WIDTH + 7 is interpreted
  as a language expression, which evaluates to 45 + 7, or 52.
  With the EXAMINE command, WIDTH + 7 is interpreted
  as an address expression: 7 bytes are added to the address
  of WIDTH, and whatever value is in the resulting address is
  reported (in this example, 131584).
