Dear Justin,

I've tried out your program and understand what you're trying to do (I
think :-). However, I think that you'd have less trouble by doing it using
strings and STR_SEP.

I've only read line2 so that you can see the workings easier, but it works
for line1 as well, in fact, it'll work no matter how many digets the
day,month or year has.

Hope this is so some help :-)

Robert

;Create a Tab character
tab = STRING(9B)

;Create 2 lines of dummy input

line1 = '10/11/99' + tab + ' 19 : 42'
line2 = '1/3/99' + tab + ' 19 : 42'

;Read line2 as a string

textline=''
READS, line2, textline
print, 'line 2 =', textline

;Use STR_SEP to break up the line into the date elements.

date = STR_SEP( textline , '/' )
help, date

day = date(0)
month = date(1)

;The last part [date(2)] will contain the year, tab and time so break
this up
;this time looking for spaces rather than slashes.

rest = STR_SEP( date(2), ' ' )
year = rest(0)

;Print out the full date

print, day
print, month
print, year

;You could continue to get the time as well
