#FRAME Built-In Function

Use #FRAME to establish a reference point for pushed variables. A subsequent

occurrence of #UNFRAME pops all variable levels pushed since the last #FRAME.

Result

#FRAME returns nothing.

Considerations

•

All variables pushed after a #FRAME are automatically popped when a matching

#UNFRAME is executed. This allows you to control local variables without having

to explicitly pop them.

•

Nesting of frames is allowed.

•

Use #VARIABLEINFO with the / FRAME / option to determine the frame level of a

particular variable.

•

#FRAME does not restrict the variable levels you can access. You can always

refer to all existing variable levels regardless of your frame.

•

If an error occurs in a macro or routine, TACL restores the frame level of all

variables to the level in effect when the macro or routine was invoked.
