Obtaining Explanations: EXPLAIN Command

There are three ways to obtain help about GILDAS tasks :

• Using command EXPLAIN: EXPLAIN Atask gives general explanations about the GILDAS task Atask, EXPLAIN Atask Apar gives more details about the parameter Apar of the task Atask.
• Using command HELP. HELP works as EXPLAIN, except when there is ambiguity between a command name and a task name. In such a case, to obtain the help for the task name, use HELP GILDAS_RUN:Atask.
• In EDIT mode of commands RUN and SUBMIT, using key GOLD ? allows to obtain help on the current task.
• In Query mode, answering ? to a prompt returns help on the current parameter.
