Formal Declaration
eaddr:eaddr (value:any)
Parameters
- value
An expression to be coerced. All types are valid.
Table 10-4 Derivation of the EADDR Bit Pattern
Parameter Type |
Action |
BOOL | 0.1 if TRUE, 0.0 if FALSE. |
U16 U32 SPTR | Set the SID part to zero. Right
justify the original value in the low-order 64 bits of the offset part with
zero fill. |
S16 S32 S64 | Set the SID part to zero. Right
justify the original value in the low-order 64 bits of the offset part with
sign extension. |
LONG Class | Transfer the SID part unchanged. Right
justify the original offset part in the low-order 64 bits of the offset
part with zero fill. |
EADDR SADDR | Transfer both parts of the address
unchanged. |
STR | Transfer the ASCII bit pattern for the last twelve
characters in the string. Strings shorter than twelve characters are
treated as if they were extended on the left with nulls. |
Examples
$nmdat > wl eaddr( 1 )
$0.1
$nmdat > wl eaddr( ffff )
$0.ffff
$nmdat > wl eaddr( 1234abcd )
$0.1234abcd
$nmdat > wl eaddr( -1 )
$0.ffffffffffffffff
$nmdat > wl eaddr( 1234.5678 )
$1234.5678
$nmdat > wl eaddr( true )
$0.1
$nmdat > wl eaddr( prog(1.2) )
$1.2
