SYSFILE Macro Command

Checks if a system file exists.

The command format is similar to the !FILE command:

!sysfile <var>=<pathname>

where <var> is a substitution variable which is set to '1' if the file indicated by <pathname> exists, otherwise <var> is set to 0.

The <pathname> may optionally be specified by means of a substitution variable. If necessary, its length will be truncated to 56 characters. Note that the existence of a file does not imply that the file is readable.

Example

!sysfile $exists#=COLLARS.ASC

If the file COLLARS.ASC exists, $exists# will be set to '1', otherwise, $exists# will contain '0'.
