There is not enough memory for QuickPascal. Check that
you are not running QuickPascal from a shell──using the
DOS Shell command in the File menu. If that isn't the
problem, try to restart QuickPascal using the /SWAP:DISK
option as follows:
QP /SWAP:DISK
The /SWAP:DISK option tells QuickPascal to store a
temporary file that it uses on disk rather than keeping
that file in memory. Note that the temporary file requires
one megabyte of disk space.
