- Introduction and Overview:
-
- This file describes the installation procedure ROSE and the format of
- files used as the basis for the installation. The files that are read
- are a PRODUCT file and an optional FIX file. The PRODUCT file contains
- all necessary information from the author of the product with all
- pre-defined options and help information for the installer. The
- optional FIX file is used to read values for installation parameters
- that where used in an earlier installation rundown. Typically, the
- author distributes a PRODUCT file and no FIX file. Under some
- circumstances it might be useful to distribute a set of pre-defined
- FIX files together with the PRODUCT file.
-
-
- ------------------------
- Operation:
-
- To install a product using ROSE enter the following command:
- ROSE productname
-
- The product name is the name of a PRODUCT file, e.g. if you received
- VieGOPHER, then enter:
- ROSE VIEGOPHR
-
- When running down the PRODUCT file, ROSE will occasionally prompt you
- for selection options. They are usually presented like this:
-
- +-------------------------------------------------------------+
- | (... some other text ...) |
- |***************************************************** |
- |The variable XYZ is used to do ... |
- |Allowed values are ABC, DEF or GHI. |
- |The predefined value is GHI. |
- |--------- |
- |1. use predefined value: GHI |
- |2. use fixed value: |
- |3. enter new value |
- |X. stop |
- +-------------------------------------------------------------+
-
- At this point you can select between the options by entering the
- code shown in the menu:
- 1. The predefined value, that is the value that is defined in the
- PRODUCT file in a #set statement.
- 2. The fixed value, that is the value which was used in the last
- ROSE run-down. That particular value was loaded from the
- FIX file.
- 3. A new value. When this code is selected enter the new value
- that you want to use in your installation on the input line.
- X. ... to abort the installation process immediately.
-
- For convenience, two short hand entries are possible:
- - Hitting ENTER alone means to use the predefined value.
- This is equivalent to option 1.
- - Entering anything other than 1, 2, 3, X, x or just ENTER
- means that this value is used a new fix value.
- This is equivalent to option 3.

- The PRODUCT file:
-
- Basically, the PRODUCT file contains information for generating the
- production modules and formatting information that is used for preparing
- the source listing.
-
-
- Syntax:
-
- Lines starting with a # sign are treated as ROSE commands, however
- text lines starting with a # sign in column 1 can be generated by
- adding an extra # sign in front to the line.
-
- general syntax:
- #command parameters ROSE command with optional parameters
- # comment commented text, not to be included
- in the module generated.
- ##line text line written as #line
- #end end of product data, processors should not read
- beyond this statement.
-
- 1. commands relevant for documentation
- #section <text> generates a LaTeX section
- #subsection <text> generates a LaTeX subsection
- #subsubsection <text> generates a LaTeX subsubsection
- #paragraph <text> generates a LaTeX paragraph
- #verbatim introduces a LaTeX block
- #endverbatim ends a LaTeX block
- #v <text> verbose text, one line
- #organize <rose> <latex> <text> /*not used*/
-
- 2. commands relevant for code generation
-
- 2.a. conditional output generation
- #switch <id> conditional output generation depending on
- the value of the variable <id>
- #case <val> output generated if variable <id> has value <val>
- #default output is generated if no #case matched
- #endswitch end of a conditional output generation section
-
- 2.b. file handling
- #erase <filename> erase the named file
- #module <filename>(opt append generated output to the named file
- possible options:
- FIX: the file is written with fixed records
- and line numbers
-
- 2.c. interaction
- #help <id> begin of help text for a variable <id>
- #endhelp
- #set <id> <val> set variable <id> to the value <val>
- #prompt <id> <val>* prompt for fix value for <id>
- if values (<val>*) are specified, the input
- is verified against them and only values from
- the list are accepted.
- #call <pgm> <id>* call the program <pgm> and replace macros
- for 0 or more ROSE variables <id>.

- Remarks:
- The program's name origins from Rose Nylund and does *not* mean anything
- fancy like 'REXX Output Synthesizer Engine' but I wouldn't mind if anyone
- prefers the second version.
-
-
- +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- To-Do list:
- + hooks: include sections of code provieded by the user
- + suppress option for fixed value if there is none
- + check out option for fixed record length option
