5.2.5 export

Syntax:

export name ;
export list_of_names ;

Purpose:

converts a local variable of a procedure to a global one.

Note:

Objects defined in a ring are not automatically exported when exporting the ring (use keepring instead).

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

See keepring.
