Maintaining Valid Rule Definitions

Since rule definitions must be syntactically correct at all times, you should consider the following issues when specifying line editing commands:

• The result of a line editing command is dependent on the line on which the command is specified. For example, the D command deletes either a single or a logical line based on the line type.
• Logical lines function as a unit and cannot be separated. For example, when a logical command is specified within a logical line, such as a subparameter line or a continuation line, the specified operation is performed on the entire logical line.
• Block commands should be specified on the main lines of the block. For example, to delete an EXECUTE block, the DB command should be specified on the EXECUTE line. To delete an IF sub-block, the DB command should be specified on either the LABEL or the IF line.

  A separator line must exist between EXECUTE blocks. Therefore, when editing multiple lines that represent entire logical blocks, separator lines (===) should be included in the line selection. In this case, BMC recommends the use of logical block commands. Logical block commands automatically include separator lines in the editing operation.

• Blank parameter lines are added automatically by Control-M/Analyzer (to enable you to specify additional parameters) and cannot be deleted.
• BMC recommends that, wherever possible, you use the D, C, M, and R commands for editing (instead of DS, DL, CS, CL, MS, ML, RS, and RL), because these commands automatically retain the logical structure of the rule definition.
