For that the MFbook definitely stresses that there is a returned value: the value of the expression that follows all the statements. If there are only statements (lines terminated by ";") it has no return value. In my mind, def's are macros (tokens are substituted verbatim), vardefs are functions. The last line, without the semicolon, functions as the "return" statement. Don't forget to follow the enddef with a semicolon. (My most common syntax error, so I now routinely search for enddef at the end of a line before I save my file and run MF.) You might also consider (where appropriate) writing your defs as vardef sinsq primary x = sind (x**2*180/pi) enddef; This gives sinsq the same syntax as sind. (x, sinsq(3x)) makes sense, of course, but so does (x, sinsq 3x) since 3x is a primary. This is what I've done in the MF/MP support files for mfpic, for the extra trig functions tand, cotd, secd and cscd not found in plain MF. -- Dan Luecking Dept. of Mathematical Sciences luecking@comp.uark.edu University of Arkansas http://comp.uark.edu/~luecking/ Fayetteville, AR 72101 From - Fri Aug 31 15:37:49 2001 Return-Path: Received: from ford.lan.haabendal.dk (pc160054.stofanet.dk [212.10.95.54]) by nef.ens.fr (8.10.1/1.01.28121999) with SMTP id f7VDbam76856 for ; Fri, 31 Aug 2001 15:37:36 +0200 (CEST) Received: (qmail 6408 invoked by uid 1000); 31 Aug 2001 13:37:35 -0000 Sender: bart@ford.lan.haabendal.dk To: pdftex@tug.org Cc: metafont@ens.fr From: Esben Haabendal Soerensen Date: 31 Aug 2001 15:37:35 +0200 Message-Id: <878zg02vvk.fsf@ford.lan.haabendal.dk> Lines: 31 User-Agent: Gnus/5.090004 (Oort Gnus v0.04) Emacs/20.7 Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="=-=-=" X-Virus-Scanner: AMaVis 0.2.0-pre6 / Virus Scan X-Loop: metafont@nef.ens.fr X-Sequence: 476 Precedence: list Subject: [metafont] Margin error with pdflatex when using ps files from metapost --=-=-= Hi I have a strange problem when compiling documents with figures using the MetaPost macros from boxes.mp. If I use either drawboxed or drawunboxed, that is when boxes.mp put some text in the output, the margin gets corrupted after the figure. It is shifted to the left. First I used the emp LaTeX package, but I have now reproduced the problem without this package. I attach two small LaTex and MetaPost files to reproduce the error.
