sorry and thanks.

i don't quite understand the assistance vgersh99 provided me.

the code given what is it for ?

---------- Post updated at 08:01 PM ---------- Previous update was at 07:59 PM ----------

lets say i read in a file...

it shows the available spaces remaining from a file

eg.

if the remaining spaces are less or equal to 9 the compiler will run & allocate without any issues (as above), but if i set remaining spaces to be more than 10 spaces out of the 20 spaces

eg.
my compiler will simply hang and not do anything.

what i need to do is... eg i tell the compiler i need 4 spaces to be allocated to the remaining gaps - automatically.
the compliler will then start checking through and slot whichever gaps it could find with B and my result should return like this for instance:

and if i need 8 spaces to be filled it will be

and if 13 spaces needed to be filled

the codes which i tried to do as show on post #1 only could work for spaces not more than 9 remaining.

eg.
