Great after using CREATE to clear out the file, avoiding any
spillover of old data into new data. Will not harm or work on
anything but random files.
FORMAT:
_._CLRAND filespec
Where "filespec" is the full file specification/name of the
random file that you want to clear out. The default extension
is ".DAT". If the filespec is left blank, directions for use
of CLRAND will be shown.
DEFAULTS:
The default is the current device and account with an extension
of ".DAT".
OPTIONS:
The only option is to leave the filespec blank, thus evoking
the CLRAND instructions.
OPERATION:
You must be logged into the OPR: account for the program to
work; you must therefore use the full filespec for the name of
the data file if it is located in some other account. ERSATZ
names for filespecs DO work. Once CLRAND has found the file,
you are asked "You are about to zero out all data in this
file. Enter Y to confirm:" Once you enter "Y", the data in
the file is history.
ERRORS:
_?Invalid file specification_
You have not properly written out the filespec so that
CLRAND can find the data file to clear. Use the _AMOS User's
Guide_ as a reference for how to write a file specification.
_Filespec is not a random file_
You are trying to clear a file that is not a random
file. It will not work.
_?This file does not exist_
CLRAND was not able to find the file that you
specified.
CHARACTERISTICS:
CLRAND is both reentrant and reusable.
