User Define Startup Blocks -- Normally the postprocessor output the default startup Prep/G-codes checked on the Default Prep Codes tab at the beginning of the machine control data file. Sometimes, it is desirable to create unique startup output blocks. Up to 10 lines of output, each with a maximum of 66 characters can be specified. Note: the postprocessor will not validate this data, so be sure it is correct. It is treated like an INSERT statement. The postprocessor will automatically append a sequence number to each line if the sequence numbers are active for INSERT statements. (starts at Intcom 3484)
