SUBTTL Edit history
COMMENT \
Edit Explanation
---- -----------
100 Rewrite entire program in an attempt to solve some major problems.
101 Fix $HELP prompt text for /NODE: specification
102 Increase PDL size from 120 to 150 words to accomodate P$HELP.
103 Weed out control characters in text message sent to the operator.
The only exceptions are bell, line-feed and carriage-return.
104 Clean up control-Z in dialogue command table.
105 Make PLEASE a single high segment linked with GLXLIB.
106 Use job number for a PID so SYSINF isn't required to run PLEASE.
107 Fix up low seg zeroing BLT to correct off by one problem.
Fixed SCAN to work right.
110 Major edit to fix:
1) Dialog mode to so that it would accept "?"
the message without a ^V quote.
2) Two prompts now apply to dialog mode. The first
explains the functions of the delimiters, the second
just prompts for the next message.
3) Made ^Z delimiter work consistently. (i.e. it will
no longer get you out if the message is null, but
rather, just prompts you for the next message without
sending the null to the OPR.)
111 Make sure the delimiter character doesn't get sent to the
operator.
112 Fix copyright. GCO 4.2.1528
130 Increase version 4.2 maintenance edit number to correspond with version
5 maintenance edit number.
