Hi

I have a string which I would like to pass into my code

The string -

SBR_1_Ammonia,01246,0.15,,SBR_2_Ammonia,01246,0.94 ,,SBR_3_Ammonia,01246,0.11,,SBR_4_Ammonia,01246,0. 01,,,


Broken down this means Name ,WeekDay ,Previous Value

There are 4 records in the string each is separated by double commas, the
end of the string is found by three commas each piece of the record is
separated with a single comma

looking at the first record it is -

SBR_1_Ammonia - Name
01246 - Monday, Tuesday, Wednesday, Friday, Sunday - Weekdays to be
included.
0.15 - Previous Value

Lets say it is monday.

The 0 indicates monday so I would like to check through the records
collecting the values which have a flag for this day.

All the records have a 0 so the string outut would look like -

SBR_1_Ammonia,01246,0.15,,SBR_2_Ammonia,01246,0.94 ,,SBR_3_Ammonia,01246,0.11,,SBR_4_Ammonia,01246,0. 01,,,


but suppose only the first and last records contained the 0 it would only
show

SBR_1_Ammonia,01246,0.15,,SBR_4_Ammonia,01246,0.01 ,,,


Thanks for your assistance with this. I want to do some other things to it
aswell but one step at a time.
