* Subject: g77 bug in assign

|
|
* I found some files in the NCAR graphics source code which used to
|
| 8 |
|
|
* compile with g77 and now don't. All contain the following combination
|
| 9 |
|
|
* of "save" and "assign". It fails on a Sun running SunOS 4.1.3 and a
|
| 10 |
|
|
* Sun running SunOS 5.5 (slightly older g77), but compiles on an
|
| 11 |
|
|
