[Guide to AmigaDOS 3\SetENV]
Format: SETENV [<name>] [<string>]
Template: NAME, STRING/F
Purpose: To set a global variable.
SETENV with <name> and <string> arguments creates a new global environment
variable. The first word after SETENV is taken as the <name>. Everything
else on the command line is taken as the <string> argument. Quotation marks
are not required. Comments (statements prefaced with a semicolon (;)) are
not allowed on a SETENV comand line. This includes command lines that are
part of a script.
SETENV with no arguments lists the current global variables. Global
variables are stored in the ENV: directory and are used by all processes.
However, if a local variable (defined by SET) and a global variable share
the same name, the local variable will be used.
Environment variables are called by scripts or other commands by including
a dollar sign ($) in front of the variable name.
To remove a global variable definition, use the UNSETENV command.
