Display the sum, difference, product, quotient and remainder of two absolute expressions.

Syntax:

ÄÄÄÄÄ H  ÄÄÄÄÄ abs-expr1 ÄÄÄÄÄ abs-expr2 ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

Parameters:

abs-expr1

An expression that resolves to a simple numeric value using any of the expression evaluator operators. Symbols of absolute values may be specified in the expression, but symbols of relocatable addresses may not.
abs-expr2
An expression that resolves to a simple numeric value using any of the expression evaluator operators. Symbols of absolute values may be specified in the expression, but symbols of relocatable addresses may not.

Results & Notes:

Each of the expressions is evaluated. If either does not resolve to a simple numeric value then the message:

Expression error

is displayed.

Having resolve each of the expressions then the sum, difference, product and quotient of the pair is displayed as in the following examples:

-------------------------------------------------------------------------------
##h 2 3
+0005  -ffff  *0006 0000  /0000 0002
#h 10t 5
+000f  -0005  *0032 0000  /0002 0000
##h 7fff 5
+8004  -7ffa  *7ffb 0002  /1999 0002
## 5*4 2*3
+001a  -000e  *0078 0000  /0003 0002
##h bmp_segsize 5
+0017  -000d  *005a 0000  /0003 0003
##h
-------------------------------------------------------------------------------

Notes

Calculations are performed using 16-bit signed arithmetic.

The operation performed is shown prefixing the result.

The product is shown as a two word value, the low word followed by the high.

The division is shown as two words, the quotient followed by the remainder.

In the last example, bmp_segsize is an absolute symbol of value 0x0012 defined in map OS2KRNL.

Evaluation of complex expressions involving relocatable addresses may be done using the ? command.
