Possibly group ASSIGN with line ...

Rule "groupassign" gives this warning when it finds several ASSIGN
statements that could have been grouped together into one single
ASSIGN statement.

Notes:

Possible issues with this rule that may need to be fixed or not:

• You can't have call a UDF an assign after writing to a key field.
• Sometimes a large assign statement is split on purpose, because there is a compiler limit for the number of characters in a single statement.
• It could be argued that intentional ASSIGN splits should all use the ASSIGN keyword. Then a variation of the rule could just report on cases where the ASSIGN keyword isn't used.
• sometimes you want separate ASSIGN statements for its NO-ERROR option.
• AppBuilder generated ASSIGN statements are not always grouped and would lead to false positives.
• Possible assign grouping within BUFFER-COPY is not checked:
  

  BUFFER-COPY customer TO ttCustomer. ASSIGN ttCustomer.customer-name = 'Old Name'. /* May be grouped with Buffer-Copy statement */
