| * Subject: g77 bug in assign |
| * |
| * I found some files in the NCAR graphics source code which used to |
| * compile with g77 and now don't. All contain the following combination |
| * of "save" and "assign". It fails on a Sun running SunOS 4.1.3 and a |
| * Sun running SunOS 5.5 (slightly older g77), but compiles on an |
| * IBM/RS6000: |
| * |
| C |
| SUBROUTINE QUICK |
| SAVE |
| C |
| ASSIGN 101 TO JUMP |
| 101 Continue |
| C |
| RETURN |
| END |
| * |
| * Everything else in the NCAR distribution compiled, including quite a |
| * few C routines. |
