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

1398 The general format of a variable expansion is:
1401 .D1 Ic \&${ Ar variable\| Oo Ic \&: Ar modifier\| Oo Ic \&: No ... Oc Oc Ic \&}
1408 A list of indirect modifiers can be specified via a variable, as follows:
1414 .Ic \&${ Ar variable Ic \&:${ Ar modifier_variable Ic \&} Oo Ic \&: No ... Oc Ic \&}
1421 since that colon already occurs in the referencing variable.
