POCKET-PAD
( -- addr )(
)
;
p4:"pocket-pad";
Returns the next pocket. A pocket has usually the size of a maxstring, see ENVIRONMENT /STRING (but can be configured to be different, mostly when MAXPATH > /STRING ) Note that a pocket is a temporary and forth internal functions do sometimes call POCKET-PAD too, especially when building filenames and getting a literal (but temporary) string from the keyboard. Functions are not expected to hold references to this transient area any longer than building a name and calling another word with it.
Usage of a pocket pad is a good way to make local temporary buffers superfluous that are only used to construct a temporary string that usually gets swallowed by another function.
depracated code: create temp-buffer 255 allot : make-temp ( str buf ) temp-buffer place " .tmp" count temp-buffer append temp-buffer count make-file ; replace with this: : make-temp ( str buf ) pocket-pad >r r place " .tmp" count r append r> count make-file ;
