Hi folks,
Which is the best way to extract the numbers of the following string ?
HELP, /MEM, OUTPUT=str
PRINT, str
I'm trying something like:
str_out=STREGEX(str,'[0-9]*',/EXTRACT)
But nothing happens...
Any suggestions ? Thanks in advance,
nata

Try using + instead of *:
IDL> print, str
heap memory used: 1302373, max: 1305378, gets: 1518, frees:
609
IDL> print, stregex(str, '[0-9]+', /extract)
1302373
Also, check out the MEMORY function.
