#11893

Posted by: Michael S 2007-09-23 11:09:08

Ru the following code


temp.0 = 9
temp.1 = 'hello      09/03/2007-10:00'
temp.2 = 'hellohello 12/03/2007-11:00'
temp.3 = 'adam       12/04/2007-12:00'
temp.4 = 'eve        12/03/2007-10:00'
temp.5 = 'stockholm  12/03/2005-10:23'
temp.6 = 'london     28/05/2007-12:32'
temp.7 = 'me         12/03/2007-12:12'
temp.8 = 'yes        12/03/2007-12:12'
temp.9 = 'no         12/03/2007-12:12'

SORT temp. 18 a +4 15 b +2 12 c +2

DO i = 1 TO temp.0
	SAY 'temp.'i' = 'temp.i
END

SAY '*****************************'
temp.0 = 9
temp.1 = 'hello      09/03/2007-10:00'
temp.2 = 'hellohello 12/03/2007-11:00'
temp.3 = 'adam       12/04/2007-12:00'
temp.4 = 'eve        12/03/2007-10:00'
temp.5 = 'stockholm  12/03/2005-10:23'
temp.6 = 'london     28/05/2007-12:32'
temp.7 = 'me         12/03/2007-12:12'
temp.8 = 'yes        12/03/2007-12:12'
temp.9 = 'no         12/03/2007-12:12'

off1 = 18 ; off2 = 15 ; off3 = 12
SORT temp. (off1) a +4 (off2) b +2 (off3) c +2

DO i = 1 TO temp.0
	SAY 'temp.'i' = 'temp.i
END

SAY '*****************************'

The idea behind it is to sort the dates on yyyy, mm and dd. As can be seen, the only difference between the two variations is that one contains variables as offsets rather than hard-coded.

unless i missed it, i couldn't find any reference to using an offset value in paren's
only string to parse on. Both the sort & parse.
so maybe the sort is using the string '18' to parse the record on, causing strange results.

I would use:
SORT temp. . c '/' b '/' a '-'
for this example
