632 Assign the value to the variable.
635 Append the value to the current value of the variable,
638 Assign the value to the variable if it is not already defined.
640 Expand the value, then assign it to the variable.
646 This can cause problems when variable modifiers are used.
650 then assign the output from the child's standard output to the variable.
657 In other contexts (most variable modifiers, string literals in conditions),
665 If the variable name consists of only a single character
670 If the variable name contains a dollar, the name itself is expanded first.
671 This allows almost arbitrary variable names, however names containing dollar,

1391 The general format of a variable expansion is:
1394 .D1 Ic \&${ Ar variable\| Oo Ic \&: Ar modifier\| Oo Ic \&: No ... Oc Oc Ic \&}
1401 A list of indirect modifiers can be specified via a variable, as follows:
1407 .Ic \&${ Ar variable Ic \&:${ Ar modifier_variable Ic \&} Oo Ic \&: No ... Oc Ic \&}
