Q36798: Microsoft System Journal M macros Fail

Article: Q36798
Product(s): See article
Version(s): 1.00 1.01 | 1.00 1.01
Operating System(s): MS-DOS | OS/2
Keyword(s): ENDUSER | | mspl13_basic

In the September 1988 issue of the "MS System Journal," the article
entitled "Customizing the Features of the M Editor Using Macros and C
Extensions" contains erroneous examples.

Both of the macros below fail in Version 1.00. Only the Bigprint macro
fails in Version 1.01.

The following is an example:

Macro 1)

;print selected text macro
print1:= copy arg "<clipboard>" setfile
print2:= arg arg "TEMP.DAT" setfile setfile
print3:= arg "PRINT TEMP.DAT" shell
print4:= arg "DEL TEMP.DAT" shell
printa:=print1 print2 print3 print4
Printa:alt+P

The above macro is supposed to print selected text. In M Version 1.00
it works correctly the first time it is called from inside a file.
However, it fails on subsequent calls to the macro prior to exiting
the file. It does work correctly in the unreleased Version 1.01
referenced in the article.

The following macro is supposed to print the entire file. Instead, it
prints only the line on which the cursor sits when the macro is
called. As mentioned above, this fails in both Versions 1.00 and the
unreleased Version 1.01 referred to in the article on Pages 59-72.

The following is an example:

Macro 2)

;bigprint macro to print entire file
select1:= arg ppage
select2:= arg arg "endoffile" mark
select3:= arg mpage
select4:= arg "endoffile"
selectall:= select1 select2 select3 select4
bigprint:=meta +>nometa cancel selectall meta :>nometa meta printa

bigprint:Alt+z
;end of bigfoot macro.
