I was looking through an old PC Magazine (9-12-89) that addressed a
problem Tom Hammond was having & I thought I'd pass it on to all.  In a
letter to the "Languages" section, James Orleff writes:

I purchased QuickBasic...to handle data arrays as large as available
memory... According to the manual, creating an array larger than 64K
requires using the $DYNAMIC metacommand and the /AH compile
switch...Even though more than 300K available..."Subscript out of range
error".

SOLUTION: Because length of each string in array was not an even power
of 2, the last string that fit in a 64K segment did not end on a segment
boundary...QB can only handle **one** intersegment gap in an array.
Limiting the size to 128K.  Though I only needed 80 bytes per element, I
increased it to 128 bytes.  Therefore, Tom, you need to change your 70
byte string to 64 or 128.  gp
