Sets a new value for a global variable. If the variable does not exist, the system creates a new global variable.
[in] Global variable name.
[in] The new numerical value.
A global variable name should not exceed 63 characters. Characters not belonging to the current code page are not allowed (characters that cannot be converted from Unicode to ANSI are replaced with '?'). If programs are to be distributed among users with different code pages, we strongly recommend using Latin characters in global variable names.
Global variables exist in the client terminal during 4 weeks since their last use, then they are automatically deleted.
