Creating a new number sequence is achieved by creating a new reference for the sequence. Follow these steps to create a new number sequence: 1. Create a new Extended Data Type (EDT). Often this EDT extends num. This is not mandatory, but it is a best practice. 2. Decide which module’s parameters this number sequence reference should be included in, and find the corresponding NumberSeqReference sub class. 3. The loadModule() method shows a number of blocks of code, which creates records in the table NumberSequenceReference. 4. Copy one of these blocks and change the following fields: a. DataTypeID is the type Id of the new data type. b. referenceLabel is the description shown in the left column of the Number sequence tab on the parameters form. c. referenceHelp is the longer description of the reference shown in the top part of the Number sequence tab of the parameters form. d. sortfield defines the sequence that the references are displayed on the Num...
