To 'GUI' or Not to 'GUI'
If you have a mixed environment, with some users connecting with terminal emulation, and some with a GUI interface, it might be handy to be able to tell which interface is currently being used. Here are two techniques:
* Are we character or are we GUI (Presentation Manager)? * A presentation manager session has '-f=The above technique also demonstrates the use of RT_GETPARAM to check for arguments on the command line. TEMP 80 contains the parameter we are interested in ('-f' in this case). After calling RT_GETPARAM, TEMP 80 will either contain the data on the right hand side of '-f=', or it will still contain '-f' if '-f' is not found on the command line. This approach does not distinguish between the Java Client and the Presentation Manager client.
Another approach is:
PASS --- FEATURE TOKEN SCANLIST FIELD SHARE? Y CALL ,RT_CHECK_CLI_FEATURE RESIDENT? N END? N FAIL 0 IF --- RETURN CODE EQ +1 T It's the Java Client F It's notThis technique specifically tests for the Java client, and will return +0 if the user is character or Presentation Manager.
