Extracting selected variables from the hpgenselect procedure using code

Several SAS procedures generate code from which the user may extract critical information.

In the example below I extract variables selected by proc hpgenselect and input these to proc corr and proc gampl without writing intermediate results to the harddrive:



The generated sourcecode 'code' is read a line at the time. Appropriate text lines are kept and concatenated into a single string using retained variables for identification (expr) and text (text).
The variable containing variable names are stored in a macro variable 'variables' and a data file test in the work library. The list may be inspected in both the data file work.test or in the SAS log.

HackRF on Windows 8

This technical note is based on an extract from thread. I have made several changes and added recommendations. I have experienced lot of latency using GnuRadio and HackRF on Pentoo Linux, so I wanted to try out GnuRadio on Windows.



HackRF One is a transceiver, so besides SDR capabilities, it can also transmit signals, inkluding sweeping a given range, uniform and Gaussian signals. Pentoo Linux provides the most direct access to HackRF and toolboxes. Install Pentoo Linux on a separate drive, then you can use osmocom_siggen from a terminal to transmit signals such as near-field GSM bursts, which will only be detectable within a meter.









Installation of MGWin and cmake: Download and install the following packages:
- MinGW Setup (Go to the Installer directory and download setup file)
- CMake (I am using CMake 3.2.2 and I installed it in C:\CMake, this path is important in the commands we must send in the MinGW shell)
Download and extract the packages respectively in the path C:\MinGW\msys\…

Alder/korrekt århundrede udfra cpr nummer

De fleste, der arbejder med registre eller databaser, står ofte med problemstillingen, at alder er uoplyst, medens cpr-nummer er kendt. Hvordan regner man den ud?

Følgende regel er gældende: Hvis syvende ciffer er 0, 1, 2 eller 3 er man født i det 20. århunderede (1900-tallet) Ligeledes, hvis syvende ciffer er 4 eller 9, og årstallet (femte og sjette ciffer) er større end eller lig 37.

Endelig er man født i det 19. århundrede (1800-tallet) hvis syvende ciffer er 5, 6, 7 eller 8 og årstallet er større end eller lig 58.

Nedenfor finder du eksempel i SAS kode: En lille makro, der udover fødselsdato også udregner køn samt den præcise alder givet datovariabel.
