- GEMDOS.BAT - A user friendly DOS shell for GEM
- ~~~~~~~~~~
- The GEM environment, as in the GEM Desktop Version 2.0 given with the
- AMSTRAD PC1512, does not provide easy means with which to type in commands
- not covered by its own pull-down menus. A notable omission is the inability
- to look at the contents of text files, e.g. the DOS TYPE command, and
- others.
-
- To cover for the above shortage there is a DOS shell command, «ENTER DOS
- COMMANDS» in the «OPTIONS» pull-down menu. This command, however, is not
- user friendly, since it always shells out into the root directory, C:\ in
- my case.
-
- The GEMDOS.BAT file serves to overcome the above limitations by providing
- the following features:
-
- 1. Double clicking on its ICON in its specified directory (A:\GEMAPPS in
- the provided example) will cause a shell into the GEMAPPS directory.
-
- 2. Copying it into any other directory (i.e. dragging with the mouse) and
- then double clicking on the new copy, will cause a shell into the chosen
- directory. The new copy of the GEMDOS.BAT file will be automatically
- removed from the chosen directory.
-
- 3. In either of the above two cases, this DOS shell utility allows typing
- in a DOS command whilst still in the GEM environment. This command is
- typed into the GEM «ENTER PARAMETERS» window which appears immediately
- after double clicking on the ICON. The command may be constructed of up
- to 10 words (9 interleaving spaces), inclusive of all its usual switches
- and parameters; however, piping and redirection symbols " | < and > "
- are not permitted.
-
- The TYPE command, probably the most common use for this batch file, is
- treated with the MORE filter, so as to get one screen full of
- information at a time.
-
-
- THE SPECIFIED DIRECTORY:
- Since the program needs to know which copy of GEMDOS.BAT it is to delete
- during a shell and which it is to keep, its default directory is specified
- in line 5 of the file. It takes the form:
-
- A:\GEMAPPS\GEMDOS GemDoS %0 %1 %2 %3 %4 %5 %6 %7 %8 %9
- ~~~~~~~~~~
- The underlined part of which may be edited to indicate the correct drive and
- directory, e.g., C:\GEMAPPS, C:\BATCH, etc.
