Sorry for jumping in VERY late.
If you have something like
DCL X CHAR (6);
X = DATE;
then you will get strange results, because DATE is not recognized as
the
well-known builtin function DATE which returns the
current date. But instead it is a DECIMAL FLOAT(6) variable
Not when you specify explicit declarations.
In his case, the identifier is marked as not declared, and it is treated
as a compile-time ERROR.
The default in PL/I (F) days for undeclared identifiers whose initial
letter was A-H and O-Z was FLOAT BINARY.
with an undefined value (given the "normal" default rules, inherited
from FORTRAN, which defines an undefined variable depending on its
first letter ... and, of course, if you don't have the more
modern compiler options which prevent you from using undefined
variables etc.).
Now, if you want the compiler to use the builtin function DATE instead
of this undefined variable, you have two choices:
- declare DATE as a BUILTIN function
DCL DATE BUILTIN;
X = DATE;
- put parantheses after DATE; that is:
X = DATE ();
this way, DATE is known to be the BUILTIN function "by context".
Both variants will do.
Same goes for all other builtin functions without arguments.
HTH,
kind regards
