# callproc, callproclsa

Purpose
Call a public procedure with the given name.
Synopsis
`function callproc(proc:string|any):reflecterror`
`function callproc(proc:string|any, p1, p2...):reflecterror`
`function callproclsa(proc:string|any, lsa:list):reflecterror`
Arguments

proc | The name or a reference to the procedure to call
pi | Parameters of the procedure
lsa | List of parameters of the procedure

Return value
The error status as a reflecterror
Example
The following Mosel code:

    public procedure myproc(i:integer)
     writeln('hello world ',i);
    end-procedure

    callproc('myproc',333)

produces this output:

    hello world 333

Further information
1. When used with a name this routine selects the procedure to call based on the provided arguments without performing any conversion (for instance, using an integer where a real is expected will not work). The execution will terminate on a runtime error if no compatible procedure can be found.
2. The last version of the subroutine makes it possible to pass all the subroutine parameters via a single list.
3. The execution status of the function is notified via its return value. If this value is ignored ( i.e. the function is used as a procedure) the execution of the model will be interrupted in case of error ( e.g. routine not found or invalid number or type of parameters).
