This function searches the local variable symbol table to find the local variable with the name stored in T{pEx->Buffer}. If the variable was not declared and the argument iInsert is true then then this function inserts the variable into the symbol table, but nothing more: the symbol table entry remains NULL.
void **ex_LookupLocalVariable(peXobject pEx,
int iInsert
){
The function returns pointer to the pointer stored in the symbol table associated with the global
variable.
