+ source/common/hbdate.c
+ tests/ddate.prg
+ tests/switch.prg
+added support for DATE type constants in the following format:
0dYYYYMMDD
for example (see tests/ddate.prg for more):
IF( dDate > 0d20051112 )
+added support for SWITCH command (see tests/switch.prg)
SWITCH <expr>
CASE <integer_expression>
...
[EXIT]
CASE <string_expression>
...
[EXIT]
[OTHERWISE]
...
END
Notice:
- Integer and string expressions can be mixed in a single
SWITCH command with no runtime errors;
- CASE expression have to be resolved at compile time and
the result has to be either an integer or string constant
- if there is no EXIT statement then next CASE is executed
(or OTHERWISE for the last CASE)
For example:
CASE 1+32+2*4
CASE CHR(64)
CASE ASC('A')
CASE "A"+CHR(13)
Notice:
The above changes apply only to FLEX version!
