Go backward to Filtering operators (PASSES,FAILS)
Go up to If...else...command (single sortword environment)
Go forward to Gate-testing operator (GATEDBY)
Masking operator (MASKEDBY)
IF <sortword>|(<expression>) MASKEDBY <16-bit mask-value> ...
IF...MASKEDBY is true only
if all the bits set in the 16-bit mask are present in the sortword or
expression being tested, eg.
IF GAMA MASKEDBY %00110101 INC SPEC1(MB1)
causes SPEC1 to be incremented if all the bits set in
GAMA are also set in the bit pattern %00110101.
IF <sortword>|(<expression>) MASKEDBY <bitmask-set-name> ...
This form of the command is true if there is a bit pattern in
<bitmask-set-name> for which all the bits set are present in
<sortword> or <expression>.
The gate number of the bit pattern which satisfies this condition
is placed in the reserved word GATE.
