Does anyone have any idea on how to read a text document (that is greater
than 16K in size) into a HyperTalk container ?
The problem is if you execute the following statement...
read from file FILENAME for NUMCHARS
where FILENAME is the name of the file and NUMCHARS contains the number of
characters in the file.
Lets say that NUMCHARS contained "20480" (ie. 20K), the read statement would
only read-in 16K of characters as it assumes (i think) NUMCHARS is an
integer (integers go up to 16K) !!
The same problem occurs if you use the "read until CHAR" statement; it will
only read in the first 16K characters !
Has anyone solved this problem? With an XCMD perhaps ?
Thanks in advance.

>Does anyone have any idea on how to read a text document (that is greater >than 16K in size) into a HyperTalk container ? It is very simple. A HyperTalk variable is only limited by RAM. Try this: put empty into theText -- clear a variable named theText repeat read from file "foo" for 16384 -- maximum chars to read if it is empty then exit repeat -- end of file put it after theText -- otherwise append to variable end repeat if the length of theText > 30000 then answer "This will not fit into a single field" with "OK" end if put theText info field 1 -- or whatever you want to do This particular script would check to see if it is larger than the limit of characters for a single field. You could process the text and distribute it across several fields if you wanted. The possibilities are endless...
