Fill-in fields:
Fill-In fields are used to set up testing of the color table memories. There are two types of fill-ins, one which is set by the user clicking the field label then typing something, the other which is set by cycling options that appear in the labels for that field. The next option appears each time the label is clicked. Fields are:
PASSES: a pass counter for the table tests. User should not change PASSES.
Read/Write: chooses testing mode. Options are WriteReadCheck, WriteRead (no checking), WriteOnly, ReadAndCheck (writes once, then repeatedly reads and checks), ReadAndShow (writes once, then repeatedly reads, checks, and displays data read), ReadOnly, Sweep (test for addressing failures - long test).
Table: chooses table(s) to test. Options are ALL, A, B, C. ALL doesn't always make sense, depending on test mode.
PatternAction: chooses pattern modification during testing. Options are Random, Fixed (no change from original Pattern), Cycle (cycles orginal pattern), and Count (sequentially counts from original pattern; Pattern=0 is likely the most useful).
Pattern: user enters 8 OCTAL digits (e.g. 12345677B) for the original 24 bit pattern.
First Address: user enters first address in table to test.
Last Address: user enters last address in table to test. If Last Address>= table size, will test to end of table.
Address Increment: user enters constant increment to address during test. Test runs FROM First Address BY Address Increment UNTIL Last Address.
Reports: options are Long (full error messages), Short (types exclamation point for any error), and None (surpress error messages).
