executes commands defined in file.
filename - File to read commands from. The commands in this (ascii) file follow the syntax as on command line: - Comments start with ";" in first column. - IDL commands start with "!". - Batch execution (i.e. read commands from file) is given with the file name preceeded with "@". Parameters may be given by appending a comma separated expression list. Within the batch file the parameters may be accessed as p1..p9 (s.b.).
> @fitall,2,3 -> sets within "fitall" the variable "p1" at 2 and "p2" at 3. - Commands starting with "#" are not echoed. - Expressions in strings between "%" are evaluated: > chgrp,%2+2% -> chgrp, 4 If single mode (s.b.) is selected the filename is interpreted as a cafe command string. group - Group to change to during execution. p1..p9 - (optional) Parameters which may be used when calling the exec command. These parameters may be referenced in a script.
interactive - Read commands from currently opened command file. If no command file was opened read from standard input (this is the top level loop). Using this option opens a new processing scope with local IDL variables.
> exec,/interactive > !u = 5 > !print, u -> 5 > quit > !print,u -> variable not found single - interprete the input file as a single command line to be executed. silent - Do not echo script commands. fullbatch - Report each line of a batch file. Default is that only executable lines of batch file are shown (this allows easy logging)
noshell - Do not run external commands (i.e. commands which do not belong to the CAFE command set) in a separate shell (UNIX only). sh - Use the bourne shell when spawning external commands. autoplot - Plot after each command. idle - Process widget events when no command is entered. This setup replaces the need of the IDLE command. It also allows to run wplot and command line in parallel (!). Internally it affects the caferead procedure which uses the readline routine. Setting this keyword may cause problems of the command line editing facility in some circumstances, thus use this keyword with care.
Changes the environment according the commands executed.
The exec-command can be abbreviated with "@" (s.a.).
