Since mission definitions must be syntactically correct at all times, the user 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, command D deletes either a single or a logical line based on the line type.
Logical lines form a unit and cannot be separated.
When a logical command is specified within a logical line (that is, on 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.
A separator line must exist between blocks and cannot be deleted.
Blank parameter lines are added automatically by Control-V (to allow the user to specify additional parameters) and cannot be deleted.
BMC recommends that, wherever possible, commands D, C, M and R be used for editing (instead of DS, DL, CS, CL, MS, ML, RS and RL) because these commands automatically retain the logical structure of the mission definition.
