Thanks Denis, an interesting approach! Will have to do some reading as this is my "terra incognita"...
-Victor- --------------------------------- How about using Unix System Services shared memory and optionally semaphores? If found this, but it uses C. http://www.infodd.com/images/infodd/downloads/I33.pdf You can also do it from COBOL with the BPX1Mxx calls (like GT for get or AT for Attach), it can run unauthorized in keys 2, 8 and 9. https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.2.0/com.ibm.zos.v2r1.bpxb100/mgt.htm Hope that helps.
