The function ŒFUNTIE unties zero, one or more currently-tied
files. The syntax is:
ŒFUNTIE TIENOS
TIENOS is an integer vector of any length,
containing the tie numbers of the files to be untied. If the tie number is not in use, no error is generated. You never need to supply a pass number to
untie a file.
To untie all the files you currently have tied, use the
expression:
ŒFUNTIE ŒFNUMS
Files are automatically untied when the APL task ends. They are not automatically untied on )CLEAR
or )LOAD.
