Programming Prompts - Input Definition Sequence
The M3000 Input Definition Sequence can define two categories of inputs:
1. Header Inputs - A Header Input is one that occurs ONLY at the beginning of data entry and
is not part of a loop. As long as you respond by entering Y or YES, the
M3000 creates new Header Inputs. When you respond by entering N or NO
to the Header Input prompt, the M3000 defines all subsequent Input
Definitions as Record Inputs.
2. Record Inputs - A Record Input is all or part of a loop structure that will repeat itself and
continuously prompt for data.
NOTE: Once this input has been answered NO, all subsequent input definitions display:
RECORD INPUT instead of prompting for Header Input.
The following procedure explains the steps used to create an Input definition Sequence.
For Example: Suppose you want to create a program that prompts you for User ID, does a
MM/DD/YY Date Stamp and then loops on ITEM and QUANTITY.
Since the User ID and the Date Stamp are not part of a loop, they are Header
Inputs.
The ITEM and QUANTITY inputs are part of a Record Loop and are therefore
called Record Inputs.
Note that Header Inputs can only occur before a loop and not after.
Header Input?
A Header Input is one that occurs ONLY at the beginning of data entry and is not part of a loop
and can be selected by entering Y or YES.
A Record Input is all or part of a loop structure that will repeat itself and continuously prompt for
data, and can be selected by entering N or NO.
NOTE: Once this input has been answered NO, all subsequent input definitions display:
RECORD INPUT instead of prompting for Header Input.
Field Requirements: YES or NO (Y or N) input required.
New Screen?
A screen is defined as one or more inputs that are shown at the same time on the M3000's two row
by sixteen column display. Since it is possible to have more than one input per screen, the
program must designate whether the input is displayed on a new screen or not. To place the new
input definition on a screen by itself press Y or YES. If you want the input to be on a screen with
any previously defined inputs, press N or NO.
Field Requirements: YES or NO (Y or N) input required.
