Ski IA-64 Simulator Reference Manual 1.0L
As an example, in
xski
,
eval 64 0d64 0o64 0b100000 *main ~(((0D1234+0X10EF0)*4)<<6)+0B10001001
prints the values of the six expressions in the Main Window, as shown in Figure 4-1. The first expression is taken as a
hexadecimal number, the second as a decimal number, the third as an octal number, and the fourth as a binary number. The
fifth expression is the value at the location specified by the symbol “main” (the first 64 bits of the code bundle at that loca-
tion), and the sixth expression is the result of some arithmetic.
