This version of FLEX has some bugs fixed from previous versions, and includes on major enhancement: the INCLUDE statement (a la FORTRAN-IV-PLUS). The tape includes a FLEX task image not linked to any resident library, and should be immediately usable. It also includes the files necessary to re-build FLEX linked to an F4PRES. FLEX.DOC is the documentation for FLEX and descibes the new INCLUDE capability.
