5.2.6 export

Syntax:

export name ;
export list_of_names ;

Purpose:

converts a local variable of a procedure to a global one, that is the identifier is not removed at the end of the procedure. However, the package the variable belongs to is not changed.

Note:

Objects defined in a ring are not automatically exported when exporting the ring.

Example:

proc p1 { int i,j; export(i); intmat m; listvar(); export(m); } p1(); ==> // m [1] intmat 1 x 1 ==> // j [1] int 0 ==> // i [0] int 0 listvar(); ==> // m [0] intmat 1 x 1 ==> // i [0] int 0
