/* REXX FIRSTIME Do a process if for the first time . Written by Frank Clarke, Oldsmar, FL Impact Analysis . SYSPROC TRAPOUT Modification History 19950221 fxc "THIS WEEK" doesn't work because 'this' was in lower case and was being compared against upper case text 19950329 fxc failed on "this wednesday" because no check was being done other than 'is today the right day?'; any other day produced HELP text 19960612 fxc squeeze space out of line before rewriting; lack of this caused an odd failure in which the data continually got longer with each iteration until it was lost off the end of the file; upgrade to REXXSKEL; 19970212 fxc recognize NOUPD and NOUPDT as being equivalent; upgrade from v.960606 to v.970113; 19980604 fxc upgrade from v.970113 to v.19980225; RXSKLY2K; DECOMM; standardize; 19991103 fxc drop support for NOUPD 20010601 fxc HELP was doing a RETURN instead of an EXIT 20160714 fxc eliminate FTINIT 20161020 fxc smooth HELP-text */ address TSO /* REXXSKEL ver.19980225 */ arg parms "((" opts signal on syntax signal on novalue call TOOLKIT_INIT /* conventional start-up -*/ rc = trace(tv) info = parms /* to enable parsing */ call A_INIT /* Initialization -*/ call B_GET_FTC /* Read existing data -*/ call C_CHECK_FTC /* When did I last run?
