Hello all, As a first time user of this user group I have a few questions: 1. I am using Roff4 1.60 written by E. Bergmann. Unfortunately I have a problem. From time to time I get the following error message: "STRLN3: weird character value .." (or something like that, can't remember now) This error occurs when I try to output various formulas like: x 1 1 1 1 e = 1 + -- + -- + ... + ------ + -- 2! 3! (n-1)! n! The definitions needed to output such a formula are very long: I use the following: .sc # e^+x^-=#1#+^(^+1^-^)--^)^-2!^+#+#^(^+1^)--^)^-3!^+ etc. This line expands to 1 + 1/2! + 1/3! on paper (I hope). I frequently need to build up 2 or 3-4 formulas after another (the definitions are very long, sometimes over 2 lines of 80 characters) seperated with some text. The formulas itself are formatted just fine; but the curious error "STRLN3" occurs when Roff4 wants to output a footer at the bottom of the text. I think Roff4 can't handle such long equations of over 2 lines and is going haywire. The funny thing is that if I delete one equation from the (problem) page, the error "STRLN3" doesn't occur. The deleted equation formatted in a separate file (containing just that equation) works fine also. But the moment I put the equation back in the original text, Roff4 refuses to work correctly. Can anyone help me ??? What is causing this problem ? How can you rectify it ? Are there more known problems with this version of Roff4? Any general information about Roff is welcome also. 2. What are the ZCPR2 and ZCPR3 systems? I want to implement it on the following system: Acorn BBC model B with Acorn Z80 second processor 64K RAM, 56K free 2 * 400 K disk drives The only assembler I have is the ASM assembler included in the CP/M 2.2 package. I believe you need the MAC assembler from DR to implement ZCPR?? Thanks in advance ..Marc Chang Sing Pang ARPANET: SINGPANG%HLERUL5.BITNET@WISCVM.ARPA BITNET/EARN: SINGPANG@HLERUL5
