WINKS 4.7 PROGRAM Analysis Limitations
COMPUTER REQUIREMENTS
Computer requirements: 8MB RAM or more recommended, many
procedures will run with only 4MB, but some will not. WINKS
will run on Windows 95, 98, NT and 3.1.
GENERAL LIMITATIONS
Maximum number of fields per database - 250
Maximum length of a character field - 65

Note:Databases may be created above the 32,000 record limit,
but this is the maximum record count verified to work with
WINKS.
