SKIP builds a table of lines to be skipped for the named file.
There is enough room in the table for 50 skip specifications. Each individual line skipped counts as one specification and each range of lines skipped counts as two specifications. Whenever a file is OPEN'ed, or reOPEN'ed, its skip table is cleared. Lines which are SKIPped in a file can not be read with the READ command or by string substitution and are not used by the STAT command. In particular, note that the number of lines in the file as returned by the STAT command is the actual number of lines minus any skipped lines.
