The 26th symposium on Principles of Programming Languages (POPL99) will address fundamental principles and important innovations in the design, definition, analysis, and implementation of programming languages, programming systems, and programming interfaces. Both practical and theoretical papers are welcome.

Papers on a diversity of topics are encouraged, particularly ones that point out new directions. POPL99 is not limited to topics discussed in previous symposia or to formal approaches. Authors concerned about the appropriateness of a topic may communicate with the program chair prior to submission.

A technical summary of 5000 words or less (excluding bibliography and figures) is to be sent to the program chair. Papers will be judged on originality, significance, correctness, and clarity. The summary should clearly express the contribution of the paper, both in general and in technical terms. It is essential to identify what was accomplished, describe its significance, and explain how the paper compares with and advances previous work. Authors should make every effort to make the technical content understandable to a broad audience. Papers must describe work previously unpublished in refereed venues. Simultaneous submission to another publication outlet (conference or journal) is grounds for rejection.

Submissions must be either electronic (encouraged) or postal (discouraged). Note that the procedure for electronic submission is different this year.

• For electronic submissions:
  • A mail message with the title and a 100-200 word ASCII abstract must be received by 6:00 AM Pacific Daylight Time, Friday, July 17, 1998. Send the message to popl99@cs.berkeley.edu.

  • Papers must be received by 6:00 AM Pacific Daylight Time, Friday, July 24, 1998. Send a single message to popl99@cs.berkeley.edu (MIME attachments are allowed). The message should contain both the previously submitted title (in ASCII) and the summary, which must be Postscript that is interpretable by Ghostscript. The Postscript must use standard fonts, or include the necessary fonts, and must be prepared for USLetter (8.5"x11") or A4 page sizes. Authors who cannot meet these requirements should submit hardcopy by post instead.

• Postal submissions must be sent to the program chair by airmail and postmarked (not metered) on or before Friday, July 10, 1998; 15 copies (printed double-sided if possible) must be provided.

• All submissions must include a return postal address, a telephone number, and an email address (if available).

These are firm constraints; submissions not meeting the criteria described above will not be considered.

Receipt of the submissions will be acknowledged by email within 3 days. Authors are responsible for inquiring about the lack of a prompt acknowledgment. Submissions lost or received late due to unusual circumstances might not be considered.

Notification of the acceptance or rejection of papers will be given by Wednesday, September 30, 1998. Full versions of accepted papers must be received by Friday, November 6, 1998. Authors of accepted papers will be required to sign ACM copyright release forms.
