FSPLIT(1) BSD Reference Manual FSPLIT(1) NNAAMMEE ffsspplliitt - split a multi-routine Fortran file into individual files SSYYNNOOPPSSIISS ffsspplliitt [--ee _e_f_i_l_e] ... [_f_i_l_e] DDEESSCCRRIIPPTTIIOONN FFsspplliitt takes as input either a file or standard input containing Fortran source code. It attempts to split the input into separate routine files of the form _n_a_m_e_._f, where _n_a_m_e is the name of the program unit (e.g. function, subroutine, block data or program). The name for unnamed block data subprograms has the form _b_l_k_d_t_a_N_N_N_._f where NNN is three digits and a file of this name does not already exist. For unnamed main programs the name has the form _m_a_i_n_N_N_N_._f. If there is an error in classifying a pro- gram unit, or if _n_a_m_e_._f already exists, the program unit will be put in a file of the form _z_z_z_N_N_N_._f where _z_z_z_N_N_N_._f does not already exist. --ee _e_f_i_l_e Normally each subprogram unit is split into a separate file. When the --ee option is used, only the specified subprogram units are split into separate files. E.g.: fsplit -e readit -e doit prog.f will split readit and doit into separate files. DDIIAAGGNNOOSSTTIICCSS If names specified via the --ee option are not found, a diagnostic is writ- ten to standard error. HHIISSTTOORRYY The ffsspplliitt command appeared in 4.2BSD. AAUUTTHHOORRSS Asa Romberger and Jerry Berkman BBUUGGSS FFsspplliitt assumes the subprogram name is on the first noncomment line of the subprogram unit. Nonstandard source formats may confuse ffsspplliitt. It is hard to use --ee for unnamed main programs and block data subprograms since you must predict the created file name. 4.2 Berkeley Distribution June 6, 1993 1
