I use this pro file running in the IDL Workbench
PRO Chapter04Table99
i = 1
WHILE i LT 10 DO BEGIN
j = 1
WHILE j LE i DO BEGIN
PRINT, j, '*', i, '=' ,i * j, FORMAT = '(4X,I1,1X,A1,1X,I1,1X,A1,1X,I2,$)'
j = j +1
ENDWHILE
PRINT;, FORMAT = '(/)'
i = i + 1
ENDWHILE
END
the output in ENVI 4.7 is
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
while in ENVI 4.8 is
1 * 1 = 1
1 * 2 = 2
2 * 2 = 4
1 * 3 = 3
2 * 3 = 6
3 * 3 = 9
1 * 4 = 4
2 * 4 = 8
3 * 4 = 12
4 * 4 = 16
1 * 5 = 5
2 * 5 = 10
3 * 5 = 15
4 * 5 = 20
5 * 5 = 25
why this happened?
