Make WBAT batches 4DOS compatible
---------------------------------
1. 4DOS has an unexpected behaviour when parentheses are used in
the arguments of a CALL statement. A special 4DOS token in the
file W.BAT will fix this problem:
Please change (the first line of) the file W.BAT to: WBAT $W %&
----- ----------
2. If WBAT is supposed to run under 4DOS as well as MS-DOS, modify
W.BAT as follows:
Note: These two lines will remain untouched, because WBAT will start
writing the SET instructions in the first line that does not begin
with an @-sign.
3. Remember known 4DOS issues: %+ and %=
Avoid a plus sign immediately following a variable, like: %pos%+1,
because "%+" seems to have higer priority under 4DOS.
Solution: insert blank space, e.g. %pos% +1 (MS-DOS compatible),
or ommit the second %-sign.
The same applies to "%=", e.g. SET %name%=something. Solution ??
