/****************************************************************************
* LOAD *
* ------------------------------------------------------------------------ *
* Purpose: Loads an OS/2 program as a presentation manager icon. *
* ------------------------------------------------------------------------ *
* Type: External command, used in the OS/2 session only. *
* ------------------------------------------------------------------------ *
* Syntax: LOAD "session title" /FS|/WIN|/PM [/I] [/ICON=iconName] *
* command [options] *
* ------------------------------------------------------------------------ *
* Parameters: session title *
* This variable specifies the title of the new session as it *
* will appear in the Task Manager. The session title may be *
* up to 31 characters long and must be surrounded by *
* quotation marks. *
* *
* /FS *
* This parameter tells MS OS/2 that the application is *
* not window compatible and must be run in a full-screen *
* session. *
* *
* /WIN *
* This parameter tells MS OS/2 that the application is to be *
* run in a presentation manager window. *
* *
* /PM *
* This parameter tells MS OS/2 that the application is a *
* Presentation Manager application. *
* *
* /I *
* This parameter causes the program being loaded to inherit *
* the environment set in the CONFIG.SYS file. *
* *
* /ICON=iconName *
* This parameter is used to specify the path and file name *
* of the icon file associated with the application. *
* If the icon file is not in the current directory, the *
* full pathname of the icon file is required. *
* *
* command *
* This variable specifies the name and extension of the *
* program to be loaded. *
* *
* options *
* This variable specifies any command line arguments that *
* are to be passed to the program being loaded. *
