VARINP: Interface for Variable Input from Text Files

VARINP allows non-CODAP variable data to be added to a CODAP Case Data file. The data must be in text format and must have an associated layout. The number of records must match the number of cases in the Case Data file.

Automatic Process Generation

If a Variable Title file is specified on the program invocation line, a MAKDFL and DICTXX will be executed after VARINP.

Program Invocation

The specific syntax for program invocation varies between operating systems. This document diplays the code for the AIX version.

ssss:     The study number
opt:      (none currently supported)
CDf1:     Input Case Data file.
VEf:      Input text file.
CI:       Input layout file.  It must conform to the CODAP standard
	  layout format.
CDf2:     Output Case Data file.
VTf:      Output Variable Title file (optional).

Variable Request Cards


These cards list the  names of variables from the layout to be added to the case
data  file.  The type specifier indicates whether the variable is to be added as
a computed or background variable.  The  variable name requested is only used to
find the input variable.  The variable name on output will be  indexed according
to  existing variables on the  input file.   These  cards are terminated  by an
'@EOF' or end-of-file condition.


<name>=<type>

name:     The actual variable name from the layout.
=:        The literal '='
type:     The  output variable  type. 'C' equals computed,
	  'V'  equals background.


Example

@codap varinp - ssss cd100 ve100 layout cd101 vt101
V0001R=V
V0002R=V
V0003R=V
V0004I=V
V0005I=V
V0006I=C
V0007I=C
V0008I=C
V0009R=C
V0010R=C
V0011R=C
@EOF


This VARINP will add V0001 through V0005 as new background variables and
V0006 through V0011 as new computed variables. The variable titles will be
updated, followed by a MAKDFL and DICTXX run.
