Description

The := inline assignment operator is used to assign a value to a field or memory variable. Assignment can also be achieved using the STORE command or '=' operator in the case of memory variables and the REPLACE command for fields. The tables alias name and alias operator, '->' must be specified when assigning a value to a field. If these are missing, the target is assumed to be a memory variable and is created as a PRIVATE memory variable if it does not already exist. The 'm->' memory alias pointer can be specified, but is not required.

Example

use names
? "mid_name='",mid_name, "'"
//Create memvar 'mid_name'
mid_name := "James"
replace names->mid_name with ""
//Assign value to field 'mid_name'
names->mid_name := "James"
m_name := "James"
? "mid_name='",mid_name, "'"
? "mid_name='",m->mid_name, "'"
? "m_name='",m_name,"'"
