I've run into a problem while writing a batch file. To illustrate,
consider the following:
SET A=HI
SET B=THERE
ECHO %A% %B%
In DOS 2.1 and 3.3 the batch file has the desired effect: HI THERE is
echoed. In DOS 3.0, only HI is echoed. In fact, in DOS 3.0 the first
%name% terminates the line. I really need the ability to concatenate
string variables, but I don't see how to do it in DOS 3.0. Any words
of wisdom out there? This must be a widely-known bug in a single DOS
version, but I've never heard of it before.

The general rule for MS-DOS, violations of which are unknown, is that MS-DOS version n.0 always has many bugs, and one should always wait for version n.10 or higher. You might try this: set A=HI set B=THERE ... set MSG=%A% %B% echo %MSG% set MSG= The last line recovers lost environment space. -- Rahul Dhesi <dhesi@bsu-cs.bsu.edu> UUCP: ...!{iuvax,pur-ee}!bsu-cs!dhesi
