There are four condition commands, file, nofile, gestalt, and nogestalt. If they resolve to ‘true’ then the command which issued them, or the page that issued them, will load.
There is a basic structure to the condition command:
Command•Path or Gestalt Selector•Filename or Gestalt Value
Examples:
nofile•<Extensions>•Test If this file exists then false
file•<Extensions>•Test If this file exists then true
nofile•<Extensions>•Test If this folder exists then false
file•<Extensions>•Test If this folder exists then true
nogestalt•otra•103 If the gestalt for ‘otra’ > 103 then false
gestalt•otra•103 If the gestalt for ‘otra’ > 103 then true
nohgestalt•otra•103 If the hexadecimal gestalt for ‘otra’ > 103 then false
hgestalt•otra•103 If the hexadecimal gestalt for ‘otra’ > 103 then true
