MAKDFL: Create Variable Title File

Last updated 19 Nov 97

MAKDFL will read a Case Data file and extract the variable titles. These titles, along with the file communications region are written on the output Variable Titles file (VTf) also known as the Definition file (DFILE) or Dictionary Title file.

Automatic Process Generation

MAKDFL will generate and add a DICTXX runstream if the P option is specified on the program invocation line.

Program Invocation

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

@codap makdfl <opt> <ssss> <CDf> <VTf>

opt:  P   Print listing of variable definitions
ssss:     The study number
CDf:      Input Case Data file
VTf:      Output Variable Title file (DFILE)

Example

@codap makdfl - cd100 vt100

The file cd100 will be read and the output file produced will be vt100. This output file will be a random access file containing the variable titles found on the input file.
