          CPMRSX is a RSX - version of the program CPMDEC, used in
          RT-11 environment. The original version is included as
          CPMDEC.FOR.



          So also read CPMDEC.DOC, which is the original description
          of this program.

          Required: RSX-11M (V3.2 was used) and FORTRAN-compiler.



          To get the program to work, edit the files:



          CPMRSX.CMD and CPMRSX.TKB



          to match your system-configuration. The program was compiled
          with F4P V3.0 without errors. Since F4P-lib is not the
          default library in our system, we have to link in this way.
          ( See CPMRSX.TKB) With FOR V02.2-5 the compilation gave 3
          warnings, which we do not understand, but the program was
          working properly.



          ***** restriction 1:



          The following commands of CPMDEC are tested and working in
          CPMRSX:
          1              display CP/M directory
          2              print (SPOOL) CP/M directory
          3              copy a file from CP/M disk
          4              copy all files from CP/M disk
          9              quit



          All others are not testet, or are not working properly. If
          you need those - go to work. ( May be CPMDEC.FOR will be
          helpfull, this is the original program.)



          ##### improvement 1



          Using the command 3, you will be able to use '*' as a
          wildcard, the same way you are used to it from RSX.



          ***** restriction 2



          Since RT-11 and RSX use different file-formats, this program
          changes the format, when ASCII-mode is used.











          The different I/O structure of FORTRAN makes it necessary,
          to send an additional blank at the beginning of each line.
          This blank is ncessary to print without loosing the first
          character in the line. EDI will show you these blanks.
          The case, you want to get rid of this, you may use the
          following procedure:
          EDI your file, using MACRO of EDI:
          EDI file
          MACRO 1 F C / //M ! watch, there are 2 blanks after F
          V OFF           ! switch VERIFY off
          M               ! execute the macro
          It may be necessary, to do this several times, getting the
          next page with REN.
          When you print this file, the first character in each line
          is not printed, due to the flag in the file-header, that
          this file is a FORTRAN-generated file.
          To change this, use EDI:
          EDI newfile
          Change from INPUT-mode to command mode
          OP file         ! open secondary file
          SS              ! select secondary file
          PAG 1           ! read all pages
          CLOSES          ! clos secondary file
          SP              ! select primary file
          ED              ! exit EDI
          This newfile will be in the correct form!



          ***** programming style



          The work of implementing CPMDEC into RSX was done in a
          hurry. By this the neat and clean way of programming, done
          by RUSS BAKKE has gone lost. That's a pitty, but there was
          not the time, to do cosmetic corrections or anything more,
          than we needed.
