Library Data
. The meaning of this is that the
MES parameters are coded in a binary file, which cannot be accessed by the
editor.
Next, we want to place them in the menu labels in a different order than the
one listed above, by following these steps:
1.
Create a list containing { EQ Mpar LVARI TITLE }, by using:
„ä
@@@EQ@@@ @Mpar! !@LVARI @@TITLE
`
2.
Place contents of LVARI in the stack, by using:
@LVARI .
3.
Join the two lists by pressing
+
.
Use function ORDER (use the command catalog
‚N
) to order the
variables as shown in the list in stack level 1.
