/ks       Maximum size of Turbo Assembler's string space

/kskbytes

Usually the string size is determined automatically and does not
need to be adjusted. However, if you have a source file that
results in an 'Out of string space' message, you might want to
increase the string space size by using this option. Try
starting with a value of 100, and increase it until your program
assembles without error.

The maximum allowable value for kbytes is 255.
