2. INSTALLATION
Expanded memory (EMS)
Extended memory (XMS)
EMS and/or XMS of 4 Mbytes or more
(recommended) (Kate 1)
* Better to include EMS of 256 kbyte
or more
(Note 2)
Note 1) The quantity of the EMS and XMS memory effects on the performance to handle
Symbol data and Net comment.
Please prepare enough EMS or XMS memory
specially for Symbol data or Net comment of large number.
Note 2) At the system with EMS less than 256 kbytes, the maximum number of steps which
FAPT LADDER can handle may be restricted. Please prepare 256 kbytes or more
EMS if possible.
About size of EMS and XMS memory to be used:
Although FAPT LADDER runs with no EMS nor XMS, enough size of EMS and/or XMS memory
according to the source program to handle will be necessary for better performance.

EMS memory for Ladder sequence program
FAPT LADDER uses EMS memory for Ladder sequence program if available.
When no EMS memory is found,
the convenGonal memory is used, and the size of
conventional memory may restrict the number of steps able to be edited.
Ladder sequence program occupies 256 kbyte of EMS, regardless of the type of PMC, or
the size of the ladder sequence program to edit.
EMS and XMS memory for Symbol & Comment data
FAPT LADDER uses EMS and/or XMS memory for Symbol & Comment data if available.
When neither of them are available, FAPT LADDER will make temporary file on the hard
drive, and processing large number of Symbol & Comment data may be slower.
About 200 kbytes of EMS or XMS memory are used for every 1,000 Symbol data.
EMS and XMS memory for Net comment
For Net comment, FAPT LADDER also uses EMS and/or XMS memory, or temporary file
as same as Symbol & Comment data.
About 200 to 300 kbytes of EMS or XMS memory are used for every 1,000 Net comments.
(3) Using a Japanese language input FEP
FAPT LADDER for PC9801 allows comments in Japanese to be entered on the symbol and
comment editing screen. (See Section 51.3.)
For Japanese language input, a front-end processor (FEP) for Japanese language input is
required.
For information about the installation and operation of an FEP, see the relevant
manual.
