| 4 | This directory contains source for a version of yacc needed by the Pascal | |
| 5 | parser. The differences between this yacc and a stadard version 6 yacc | |
| 6 | are indicated in a comment in y1.c. | |
| 7 | ||
| 8 | Note that the standard yacc parser will not work on the tables produced | |
| 9 | by "eyacc" and also that these changes are really useful only with | |
| 10 | a fairly large set of error recovery routines which are part of both | |
| 11 | "pi" and "pxp". The routines are language independent, but the method | |
| 12 | will only work on languages which have some redundancy in them... it is | |
| 13 | probably ill suited for C, but would work fine in ALGOL-60, ALGOL-W, | |
| 14 | EUCLID, LIS, SP/K, PL/1, ALPHARD, CLU, ... | |

| 18 | A paper describing the method used by eyacc will appear in August in the | |
| 19 | SIGPLAN Boulder conference. | |

| 23 | The eyacc in this directory has been modified to work for | |
| 24 | version 7. This involved syntax fixes and changing the I/O calls | |
| 25 | to standard version 7 calls. | |
