Here is what is going on. The distribution you grabbed (I have since updated it) has a routine in it that checks the keywords on a command by command basis. This keyword checking is controllable by the setting of a System Key Table (SYSKEY.TAB) entry, meaning that you can turn off the checking by simply running: SYSVAL CHANGE 15 1 as the user 'mcidas' while having a REDIRECTion setup to locate the copy of SYSKEY.TAB that is being updated by XCD and ldm-mcidas decoders (/var/data/xcd and /var/data/mcidas in your case). The new copy of SYSKEY.TAB that goes out with the Unidata McIDAS-X distribution has this value set so that keyword checking will be disabled. Since you have an existing McIDAS installation, and since your session(s) point at the existing SYSKEY.TAB (through REDIRECTions), you will need to change the value of entry 15 to a non-zero value (like 1). By making this change as the user 'mcidas' (who should have write access to SYSKEY.TAB (as does 'ldm')), all users McIDAS sessions will ignore keyword checking. Right after the workshop I decided that this was such a hassle to explain that I disable keyword checking in the code. People who have grabbed 7.8 after August 9 do not have to run the 'SYSVAL CHANGE 15 1' invocation to get things to work. Please run the SYSVAL CHANGE command above and then immediately try the image displays that were failing. Sorry for the hassle.
