To make the command line as flexible as
possible you must know how to save it so that it can be put back. This will give
greater leverage to certain programs from U2, for instance Callnext, where the
files in a directory are examined sequentially. You may want to search for
information in the file that appears in the adjacent window. This will erase
'callnext' from the command line. However if you save it first with another Xpl
program, it can be restored by an Xpl program when you revert to that window.
In order to achieve this I use two short
programs that is contained in Herb Tyson's book, XyWrite Revealed, with slight
modifications.
Here are the encoded versions.
Savexp. pm
XPLeNCODE v2.0
b-gin [UNTITLED] {<}SX998,{<}IS00{>}{>}[AS_][TF_][BC_]se / /{<}EX{>} -nd XPLeNCODE and Getexp. Pm
XPLeNCODE v2.0
b-gin [UNTITLED] {tab}[AS_]{<}SV18,[cr|lf]{>}{<}SV17,[255+048+065]{>}{<}LBfixc r{>}{<}IF{<}IS18{>}{238}{<}IS998{>}<0{>}{<}GLskip{>}{<}EI{>}{ <}XS998,18,71,72,73{>}{<}SX998,{<}IS71{>}+{<}IS17{>}+{<}IS73{ >}{>}{<}GLfixcr{>}{<}LBskip{>}[BC_]{<}PV998{>}[GT_][cr|lf] -nd XPLeNCODE I also use these programs with "home" which
I included in the U2 file. 'Home' enables me to edit or make changes from
the top of the screen as I find it easier than trying to do so from the middle
or at the end. It is necessary to save it when I have to obtain information from
files in adjacent so that it can be put back.
Here is the encoded version of home.
XPLeNCODE v2.0
b-gin [UNTITLED] {{;5home}}[cr|lf]{tab}{002}[DX_][GT_][LB_]{<}SX01,{<}CP{>}{>} [HM_]{<}LBtest{>}{<}SX02,{<}CP{>}{>}{<}IF{<}PV02{>}=={<}PV01{ >}{>}[DO_]{<}EX{>}{<}EI{>}[MU_]{<}GLtest{>}{002}[cr|lf] -nd XPLeNCODE There may be other u2 programs that you may
want to use in this manner.
Although we are advised to put as many of our own programs into the u2 file, I find it still more convenient to place my define and save file programs in startup.int by assigning them to keys in the keyboard file. I am interested to know whether the U2 file
contains something similar.
