H2 and H6 H2 and H6 constants generate
H2000 BCD and H6000 BCD
codes, respectively. Use of H2 and
H6 is identical to use of E and A
prefixes described in the previous
sections of this table.
Since H2000 and H6000 BCD are
defined as 6-bit codes, no
specification greater than X’3F’
generates a legal character. If
anything from X’40’ to X’FF’ is
coded, an error message appears
and the bad character is replaced
with a blank.
String constants may be replaced
by an optional repeat count. A
repeat count must be enclosed in
parentheses and must be in the
range of 1 to 255.
BLOCK CONSTANT = H2’373737’;
BLOCK CONSTANT = H6’373737’;
Repeat count examples:
T1: TABLE CONSTANT = (3)’*’;
is equivalent to:
T1: TABLE CONSTANT = (‘###’);
T1: TABLE CONSTANT=(3)O’27’;
T2: TABLE CONSTANT=(4)X’C1’;
