- Command is a shareware product from Solid Applications Inc.
- You are allowed to give a copy of the PCOMMAND.PRG program
- and this documentation to anyone for no charge. The program
- may not be sold or included as part of a package for sale without
- prior written approval from Solid Applications. We encourage
- you to distribute this package to your friends and coworkers who
- are using the Atari ST.
-
- You may register your copy of PCommand with Solid Applications
- for $25.00. You will receive a copy of the full documentation
- and a disk containing the desk accessory version of PCommand
- along with some useful utilities including a format program which
- creates diskettes that can be read on an IBM PC (both single and
- double sided disks).
-
-
-
- WHAT IS PCOMMAND:
-
- Command is a line-oriented command line interpreter with
- batch file support. It provides an interactive interface to Atari
- TOS which runs on the Atari ST. Commands are similar to PC-DOS
- commands PCommand provides faster access to TOS facilities than
- the GEM desktop. Multiple commands can be entered on a single line
- for even better efficiency.
-
- Command has a number of built-in commands which are always available
- and can run GEM or TOS-based applications by simply typing their name.
- A list of local commands is displayed by typing HELP. The batch file
- facility can be used to present GEM-based menus and alert boxes. This
- allows a GEM interface to be built using a text editor to create a
- batch file. Most text editors available for the ST will work.
-
-
-
