exec
script file execution
Calling Sequence
exec(path [,mode]) exec(fun [,mode]) ierr = exec(path, 'errcatch' [,mode]) ierr = exec(fun, 'errcatch' [,mode])
Arguments
- path
a string, the path of the script file.
- mode
an integer scalar, the execution mode (see below).
- fun
a Scilab function.
- ierr
an integer, 0 or error number.
Description
exec(path [,mode])
executes sequentially the Scilab instructions
contained in the file given by path
with an optional
execution mode mode
.
The different cases for mode
are :
- 0
the default value.
- -1
nothing is printed.
- 1
echo of each command line.
- 2
prompt
-->
is printed.- 3
echoes + prompts.
- 4
stops before each prompt. Execution resumes after a carriage return.
- 7
stops + prompts + echoes : useful mode for demos.
exec(fun [,mode])
executes function fun
as a script: no
input nor output argument nor specific variable environment. This form
is more efficient, because script code may be pre-compiled (see comp). This method for script evaluation allows to store scripts as
function in libraries.
If an error is encountered while executing, if 'errcatch'
flag is
present exec
issues no error message, aborts execution of the
instructions and resumes with ierr
equal to the error
number. If 'errcatch'
flag is not present, standard error handling
works.
Remarks
exec
files may now be used to define functions using the inline function definition syntax (see function).
exec
supports files encoded as ANSI/ASCII and UTF-8.
The length of each line in a file is limited to 4096 characters.
Examples
// create a script file mputl('a=1;b=2',TMPDIR+'/myscript') // execute it exec(TMPDIR+'/myscript') whos -name "a " // create a function deff('y=foo(x)','a=x+1;y=a^2') clear a b // call the function foo(1) // a is a variable created in the environment of the function foo // it is destroyed when foo returns whos -name "a " x=1 //create x to make it known by the script foo exec(foo) // a and y are created in the current environment whos -name "a " whos -name "y "
