A simple explanation for an SVC is that it performs system services on behalf of the application programme: OPEN, CLOSE, ABEND, etc. Most of this is hidden by the language, and the run-time, from the 'ignorant' programmer. Eg: OPEN xxxxxxxx FOR INPUT. The above eventually invokes an SVC. - Ted MacNEIL eamacn...@yahoo.ca Twitter: @TedMacNEIL ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
