Hi List, Many thanks to those who made their suggestions.=20 The TIMER block statement where DEP block went into error has no secured connection. After this error occurred I put the DEP block into AUTO and when the block ACTIVATED, codes executed without any problem. The following is the related summary; 1. DEP block went to MANUAL and its SBXs programming dumped the error code: Error:3, Stp: 1, Stmno:20. to SN0009. The Error:3 is OP_ERR 3. This error means that try to attempt a secured parameter. The statement 20 in the block is STOP_TIMER(::TIMER.TIMR3); The TIMER block in question has no secured parameter. 2. It was mentioned that TIMER is a keyword (HLBL Batch Language user Guide B0400DF Rev A) and cannot be used for block name. However many mentioned that indeed the block named TIMER used in the sequence codes without any problem and it can be used in reference to C:B:P. 3. Doug Lloyd mentioned about the script "oma" which gives description of the run time error codes; Just a reminder that many/most of the runtime error codes are documented in the /opt/fox/bin/tools/oma.exe program. Fire up oma and ask for the error code meaning at the "COMMAND:" prompt. The required syntax is "y" followed by the error code number. Think of it as "why am I getting this error". If anything more missed out let us add the same.

Thanks, Doug, for a neat trick that I haven't seen mentioned before (and I use oma regularly). I think it bears mentioned that this also works on the 51-series /opt/fox/bin/tools/oma.
