Array Sort order

???? //-1 for ascending order ??????

This code is great but I can't get it Ascending !!!! I have put -1 in various places and it gives error

WhilePrintingRecords;
stringvar Array codes := split({@array}, ", ");
stringvar Array result;
redim preserve result[ubound(codes)];
Numbervar k;
NumberVar p;
stringvar y;
numbervar i;

for k := 1 to ubound(codes) do
(
result[k] := trim(Maximum(codes));
for p := 1 to ubound(codes) do
(
if trim(codes[p]) = result[k] then
(
codes[p] := "";
Exit For;
);
);
);

for i := 1 to ubound(result) do (
y := y + result[-i] + ", " [highlight #CC0000]//-1 for ascending order[/highlight]
);
trim(left(y,len-2));

I have not examined this code. But I found some code for a bubble sort (VBA) and converted to Crystal format. It will only work with strings. I will have to find the code.

Ideal I have a Stringvar anyway but all it does id show in the descending order the I changed to his code and its still descending
effectively I have a Multi-value Dynamic Paramenter, that I use, then select data from another table related to it Everything is perfect except the sort order !!!

My fault. The comment should have read:

//-i for ascending order

...in other words, the formula will sort in ascending order as is. For descending order, remove the minus sign.

Thanks but that gives me a problem because as written if is ascending but my records are still not sorting and if I change it to I then it still doesn't work back to the drawingboard

this is my full code and it takes the list of multi value parameter and I need it in order

shared numbervar counter;
shared stringvar display;
for counter := 1 to count({?Pm-?Enter invoice Numbers}) do
(
display := display + totext({?Pm-?Enter invoice Numbers}[counter],0,"") + ", ";
);

stringvar Array codes :=display;
stringvar Array result;
redim preserve result[ubound(codes)];
Numbervar k;
NumberVar p;
stringvar y;
numbervar i;

for k := 1 to ubound(codes) do
(
result[k] := trim(Maximum(codes));
for p := 1 to ubound(codes) do
(
if trim(codes[p]) = result[k] then
(
codes[p] := "";
Exit For;
);
);
);

for i := 1 to ubound(result) do (
y := y + result[-i] + ", " //-1 for ascending order
);
trim(left(y,len-2));

Make two changes:

shared numbervar counter;
shared stringvar display;
for counter := 1 to count({?parm}) do
(
display := display + {?parm}[counter] +
if counter <> ubound({?parm}) then ", "; //this removes the final, in display
);

WhilePrintingRecords;
stringvar Array codes := split(display,", "); //you need to split display so that it is still an array

The rest of the formula is correct. Please remove the comment at the end or change the -1 to -i, just so it is not confusing to others who might read this.
