From 48dcfd22f9c2db5cf6745eaec0ff28895858c638 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Mon, 21 Jul 2025 00:19:52 +0300 Subject: support <==> and <===> for printing octal and hexadecimal numbers * These are famously in DEC TECO-11, but also in Video TECO. * The implementation is tricky. They need to use lookahead states, but this would be inacceptable during interactive execution. Therefore only if executing from the end of the command line `==` and `===` are allowed to print multiple values. The number is therefore also not popped form the stack immediately but only peeked. It's popped only when it has been decided that the command has ended. * This may break existing macros that use multiple `=` in a row to print multiple values from the stack. You will now e.g. have to insert whitespace to separate such `=` commands. --- doc/sciteco.1.in | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'doc') diff --git a/doc/sciteco.1.in b/doc/sciteco.1.in index c7ad1a9..82c3376 100644 --- a/doc/sciteco.1.in +++ b/doc/sciteco.1.in @@ -141,6 +141,10 @@ Batch mode does not have these restrictions. .IP \(bu A few commands that modify the command line are only available in interactive mode. +.IP \(bu +A few commands like \fB^C\fP are disallowed in interactive mode +when run from the command-line macro or behave slightly +differently compared to batch mode (e.g. \fB$$\fP or \fB==\fP). .RE . .LP -- cgit v1.2.3
