SUBTTL Revision history
COMMENT `
[1] 26-Mar-79 The sequence .PATH<CR> .CONTINUE<CR> caused
I/O to unassigned channel. Make CONTINUE act
the same as REENTER.
[2] 12-May-79 Change the logical name code to know about the
new format for the logical name block.
[3] 29-May-79 If PATH gets an error return trying to do a /CLEAR,
it loops forever retrying the UUO. Give up with
an appropriate message if the /CLEAR fails
[4] 07-Aug-79 If /PHYSICAL is applied to any component in a
logical name definition, PATH will ignore any
existing logical name in performing the substitution
for the component.
[5] 21-Aug-79 In search list switches where the user types
a * with no modifiers (e.g., NOCREATE), keep
the existing modifier bits for each structure
represented by the *.
[6] 15-Nov-79 APLSTK was AOBJNing on the wrong AC sometimes
causing a loop. Correct the AC.
[7] 06-Dec-79 "pa/mod:dskb:write" (note the lower case) would
result in "?PTHUSM Unknown structure modifier 7RITE"
Call .SIXSW instead of .SIXSC.
[10] 18-Jun-80 Change the job search list before changing the
default path so the user can do both in the same
command if the SFDs in the path only exist on the
structure being added.
[11] 18-Jun-80 Change the processing of /SEARCH and /LIB to
reflect the new monitor algorithm.
[12] 09-Jul-80 Change the search list switch processing routines
to do the REMOVEs then the ADDs and finally the
MODIFYs. This allows commands of the form
.PATH/REM:DSKG/ADD:DSKG which causes DSKG to be
moved to the end of the current search list.
;Start version 2 here
[13] 30-Sep-81 Change the definition of logical names to allow
filenames and extensions to be specified. Also
implement /OVERRIDE and /COMMAND.
[14] 30-Sep-81 If the user specifies no path in a component for
a logical name, zero the PPN word of the
component in the logical name block and let the
monitor fill it in.
;Revision history continued
[15] 01-May-82 If the user defined a logical name with the
[,...] construct, type the logical name back
at him with [,] instead of filling in the
PPN.
[16] 22-Mar-83 Remove the /COMMAND function since that is now
provided by another program.
Start version 3 here
[17] 01-Sep-83 Change over to use RDH's SCAN.
[20] 17-Nov-83 Add .PA=DEV: construct to change path and
add a structure if needed.
[21] 22-Nov-83 Fix bug with defaulting strs in names to DSK:
caused by [17].
[22] 03-Feb-84 Add the /UP and /DOWN switches for easy SFD level
changes in default paths.
[23] 22-Apr-84 Add the < and > constructs for easy use of UP and
DOWN type features.
[24] 29-Aug-84 .PA XX:=XPN:/L listed all pathological names,
rather than just XX:.
[25] 30-Aug-84 Improve speed of /ADD by changing the default path
into UFD level during the STRUUO (when safe).
