+# The purpose of this routine is to allocate more space for rows for a
+# text table.  If the specified row is within the range of
+# existing rows, the table itself will not be modified.
+#
+# If rownum is greater than TB_NROWS but less than TB_ALLROWS, then only
+# TB_NROWS will be updated.  If rownum is greater than TB_ALLROWS, then
+# tbzsiz will be called to reallocate space for the table columns.

+# Phil Hodge,  4-Mar-1998  Subroutine created, extracted from tbtwer.
+# Phil Hodge,  7-Jun-1999  Add TB_MAXPAR(tp) to calling sequence of tbzsiz.
