, SDCL, LANGUAGES, Structured DCL Preprocessor   03-Oct-2000, munroe@csworks.com   8 Many years ago, this preprocessor was written to provide? "structured programming" constructs (if-then-else, loops, etc.) = for DCL.  In many ways it is still more useful than "vanilla" : DCL, in particular for quickly building large, complex DCLA procedures.  It has been used here at Cottage Software Works (and ? before that at Acorn Software) for many years and, despite it's 6 limitations, provides good duty when "non-trivial" DCL programming needs to be done.    Dick Munroe   ( 02-Jun-95 Dick Munroe munroe@acornsw.com   Changes:  < 1. added an on statusCondition { statements } block to sdcl.F 2. Variable substitution ('varable') and quoted strings are preserved.D 3. Loops emit $NEXT and $BREAK variables which are labels to be used: by DCL commands such as read which have /ERROR processing.   Use it in good health.   Dick Munroe P --------------------------------------------------------------------------------G This directory contains the SDCL (Structured DCL) compiler files. These F include the source files and the documentation files. Here is what you* should have if the tape restore worked ok:  ' AAAREADME.TXT		The file you are reading   ( BUN.DCL			Example of structured DCL code  1 DEFS.H, LEX.C, OUTPUT.C, SDCL.C, STACK.C, STMT.C, 0   TCODES.H		Files with C source of SDCL compiler  F LASER.DCL,LASER.COM	another example of SDCL input and generated ouput.  3 MAKEFILE.COM		Command procedure that makes SDCL.EXE   3 SDCL.EXE		The executable file created under VMS 4.1   < SDCLPROJ.DOC		A detailed documentation on the inner workings/ 			of SDCL compiler.

If you have it,D run the command procedure in MAKEFILE.COM and then install SDCL as a foreign command:   	$ @makefile' 	$! now in your login.com, add the line " 	$ sdcl :== $[directory-path]:sdcl8 	$! replace "directory-path" with the complete directory, 	$! path name to where the sdcl.exe resides.  D If you donot have the C compiler, you can simply use the executable 1 SDCL.EXE included. It was created under VMS 4.1.    K I have compiled the sources with the UNIX C compiler on the SUN workstation L and HP-UX. The program runs without any change. This implies that you donot L have the DEC C compiler, try using the DECUS C compiler. This may, hopefully work.   J I will welcome any comments, bug reports, fixes and any other suggestions., If you make any enhancements, please let me.  
