Status Display

The application status display (one of the special status displays described in

the Attended Workstation User’s Manual) is not accessible through any

subroutines in ENV, and is not emulated in ENVPC. Use a section of code

which is conditional on the value of PcMode to set the status display.

Printing Reports and Forms

Since PRINT # USING.. is not supported, we recommend that you format

reports by first printing the report to a scratch file, then copying the file to

the device. Example:

listfile$ = “SCRATCH”

OPEN listfile$ FOR OUTPUT AS #1

PRINT #1, USING ” . . . . . . .

. . .

build your report, form, or complex response here

. . .

PRINT #1, USING ” . . . . . . .

CLOSE #1

OPEN listfile$ FOR INPUT AS #1

DO WHILE NOT EOF(1)

LINE INPUT #1, s$

SendQue s$ ‘ This could be SendQue, Send, or SendCom

LOOP

CLOSE #1

KILL listfile$

Using the ENVPC Simulator
