Error: String can be at most 65534 characters

Question

Hi,
I am using Crystal XI
I have a string variable in my formula that gathers log ids found when report is run. I then use this variable to display records in my subreports. But when I run a report with wider search criteria I get an error - Error: String can be at most 65534 characters.
How can I get rid of this error? Below is my formula
WhilePrintingRecords;
Global StringVar Array_Name;
numbervar slno;
Array_Name:= Array_Name & Cstr({PMP.LOG_ID}, 0) & ",";
if {@TimelyComplete}= 0 then
slno:= slno+ 1;
What would be an alternative solution for this problem?
Thanks for your help!

Storing the values would look something like this (basic syntax):
global vals(1) as string
global nextIndex as number
if nextindex = 0 then
  nextIndex = 1
end if
if len(vals(nextIndex)) + len({field_to_add}) > 65530 then
  nextIndex = nextIndex + 1
  redim preserve vals(nextIndex)
  vals(nextIndex) = {field_to_add}
else
  vals(nextIndex) = vals(nextIndex) + ", " + {field_to_add}
end if
