| |
| procedure Check_Indentation |
| renames Style_Inst.Check_Indentation; |
| -- Called at the start of a new statement or declaration, with Token_Ptr |
| -- pointing to the first token of the statement or declaration. The check |
| -- is that the starting column is appropriate to the indentation rules if |
| -- Token_Ptr is the first token on the line. |

| renames Style_Inst.Check_Then; |
| -- Called to check that THEN and IF keywords are appropriately positioned. |
| -- The parameters show the first characters of the two keywords. This |

| |
| procedure No_End_Name (Name : Node_Id) |
| renames Style_Inst.No_End_Name; |
| -- Called if an END is encountered where a name is allowed but not present. |
| -- The parameter is the node whose name is the name that is permitted in |

| procedure No_Exit_Name (Name : Node_Id) |
| renames Style_Inst.No_Exit_Name; |
| -- Called when exiting a named loop, but a name is not present on the EXIT. |
| -- The parameter is the node whose name should have followed EXIT, and the |
| -- scan pointer is positioned so that if an error message is to be |
| -- generated, it should be generated using Error_Msg_SP. |

| procedure Non_Lower_Case_Keyword |
| renames Style_Inst.Non_Lower_Case_Keyword; |
| -- Called if a reserved keyword is scanned which is not spelled in all |
| -- lower case letters. On entry Token_Ptr points to the keyword token. |
