# getSpaceTextLines

A text file's lines, numbered, a page at a time (`N| line`; up to 12000 characters a page from `startLine`, `totalLines` and `endLine` say where you are). For a file too large for getSpaceTextContent to return whole: read it page by page, passing the FIRST page's `versionId` on every later page so all pages come from one version, then add lines with insertSpaceTextLines by these numbers with that `versionId` as `baseVersionId` (a save since is refused, never mixed in).
