Hello again! I want to match 2 tables to have the same length, but I want to save the overage. Here is the code that didn't work because J does not seem to allow variables in place of numbers:
[leny1 is the length of the DEG table and lenx1 is the length of the table to match DEG with] xydiff=. leny1 - lenx1 NB. length leny1 must always be longer than lenx1 DEG2=. _xydiff {. DEG NB. save unmatched tail portion of DEG DEG=. _xydiff }. DEG NB. delete unmatched tail portion of DEG Since it seems (and I may be mistaken in some way) that J cannot handle the value of a noun variable, how can I accomplish what I'm trying to do in the above code? Thanks in advance for any help with this! I hope this is not something ultra obvious that I've overlooked. ;-) Harvey ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
