# setbpt

set breakpoints

## Calling Sequence

    setbpt(macroname [,linenumb])

## Arguments

macroname

  a string

linenumb

  a scalar integer or a vector of integers

## Description

`setbpt` interactively inserts a breakpoint in the line number `linenumb` (default value is 1) of the function `macroname`.

`linenumb` can be a line or column vector of line numbers, or a single scalar line number.

Line numbers in `linenumb` are physical line numbers in function `macroname`. Note that Scilab versions before 5.0 used logical line numbers. The difference between physical and logical line numbers is the number of continued lines (see dot).

When reaching a breakpoint, Scilab evaluates the specified physical line and stops the execution flow. If the function is not compiled (see comp) the line is printed on the screen. Then Scilab goes into a pause mode in which the user can check current values. The pause is exited with resume or abort.

Redefining the function does not clear the breakpoints, the user must explicitly delete breakpoints using delbpt. The maximum number of functions with breakpoints enabled must be less than 100 and the overall maximum number of breakpoints is set to 1000.

## Examples

    setbpt('foo')
    setbpt('foo',10)
    dispbpt()
    delbpt()
    setbpt('foo',[1,2,5,6])
    dispbpt()
