4. Open and close the driver for each report.

In most PL/N applications, the printer is opened at the start of a program

and closed only when chaining to another program.  IrDA drivers required

that the printer be opened just before printing a report and closed just after

finishing the report.  For applications which currently have a common

PRINTCTL routine, often named PAxxP9P, this is accomplished by moving

the open/close logic to this routine.  Remove all other opens and closes.
This change is compatible across all NORAND handĆheld computers, e.g.

4000 Series, so there is no need to include a ++IFDEF.

5. Remove Excess Linefeeds.

The report formats used for the 6805 are the same as previous 40Ćcolumn

printers.  However, the 6805 requires fewer linefeeds to sufficiently eject a

report.  Many applications feed eight lines at the end of a report on a 40ĆcolĆ

umn printer.  Reduce this to five lines for a 6805 Printer.  Also, reduce the

number of linefeeds used prior to TICKET OK?" prompts.  This saves paĆ

per and makes your reports look nicer.

IPFMCF6, the memory card format routine for the 4000 Series.  Memory on PC

Cards cards can be formatted on the PEN*KEY 6000 Series Computer by

loading the CardSoft drivers (or NORMOD drivers) and executing the

FORMAT.COM program from ROM DOS 5.

This function commits all outstanding writes on all open files and updates the

DOS directory.  It uses DOS function 5D01h.  This function can be used only on a

PEN*KEY 6000 Series platform.  On a 4000 Series, using MINI/MAXIĆDOS, use

of this function causes the system to display the message Unimplemented DOS

call" and hang.
Parameters:

None

Return Value:

Zero (0) if successful.  A return value of 257 indicates that the calling

routine incorrectly attempted to pass parameters to this function.  Any

other return value is the return value of DOS function 5D01h.
