Format
string1 = ENVIRON$(number1)
Description
This statement will retrieve DOS environment strings. Number1 identifies
which string to retrieve. If found, the string is placed in string1. If
not found, a NULL string (length=0) is stored in string1.
Example
FOR I=1 TO 5
A$=ENVIRON$(I)
PRINT A$
NEXT I
The above example will retrieve the first five DOS environment strings and
display them.
Comments
If the requested DOS environment string entry is greater than 80
characters in length, ASIC will truncate it at 80 characters. Environment
strings may be set in DOS using the SET command. Environment strings are
one way of passing information to your program. Refer to your MS DOS
Manual for more information. Common uses of this command are to retrieve
the user's PATH statement, or the COMSPEC variable.
