Yotta's SEMI P39 OASIS to Text and Text to OASIS utilities print OASIS files in an easy-to-understand text format and create OASIS files using that same format. The tools work on a record-by-record basis, so that even semantically invalid OASIS files can be studied. An arbitrary byte sequence capability allows the creation of syntactically invalid OASIS files for test purposes.

The conversion tools use a fully-specified human-readable format. Both tools support all of SEMI standard P039-0308, including CBLOCK records and repetitions. The tools are fully compatible, so that the output of oas2txt can be sent to txt2oas to create an OASIS file identical to the original input.

A "modal variable" option allows expansion of all modal variables (when converting to text) or usage of all modal variables (when converting to OASIS). There is no need to track the values of OASIS modal variables such as X and Y locations, trapezoid widths, etc., when trying to understand the geometry in a file.

New geometry records can be added to a text file without invalidating the name table offsets of the output OASIS file. Name table offsets in the END record are updated automatically when writing the file.

The file checksum or signature, if any, is automatically updated when creating an OASIS file.
