I have no idea what that broken snippet of code is supposed to be doing. I'm not also sure what you mean by nameref's, since you don't appear to be doing anything that sets any variables except the ones you already told me to ignore...
I'll take a wild guess.
One way to set arbitrary variable names is to use read.
I was wondering if there is anyway to use the curses library with ksh88. I saw Shell Curses function library which says I can use /usr/local/functions/shellcurses on ksh93 but I am on ksh88. I am on a HP-UX box. (0 Replies)
Hello,
I need ksh88 for my linux system - and I don't want pdksh.
Possible to get original ksh 88 binaries or source ?
(I don't need ksh93 which is available)
thanks

Hi I tried the following string comparison script in Ksh88
#!/bin/ksh
str1='aC'
str2='ABC'

echo "Equal"
else
echo "Not Equal"
fi
Though str1 and str2 are not equal the script output says Equal .
Please correct me

Hello,
I want to pick a random element from a list, and created these 2 lines, which work very well in ksh93. Unfortunately, I get this "bad substitution" message in ksh88.
I'm wondering if there's an equivalent to the second line of my script.. or if I have to install ksh93 to make this... (8 Replies)
I don't know if anyone is interested but I have been meddling with FFT for the AMIGA.

eval
eval(n) Tcl Built-In Commands eval(n)
__________________________________________________________________________________________________________________________________________________NAME
eval - Evaluate a Tcl script
SYNOPSIS
eval arg ?arg ...?
_________________________________________________________________DESCRIPTION
Eval takes one or more arguments, which together comprise a Tcl script containing one or more commands. Eval concatenates all its argu-
ments in the same fashion as the concat command, passes the concatenated string to the Tcl interpreter recursively, and returns the result
of that evaluation (or any error generated by it). Note that the list command quotes sequences of words in such a way that they are not
further expanded by the eval command.
EXAMPLES
Often, it is useful to store a fragment of a script in a variable and execute it later on with extra values appended. This technique is
used in a number of places throughout the Tcl core (e.g. in fcopy, lsort and trace command callbacks). This example shows how to do this
using core Tcl commands:
set script {
puts "logging now"
lappend $myCurrentLogVar
}
set myCurrentLogVar log1
# Set up a switch of logging variable part way through!
after 20000 set myCurrentLogVar log2
for {set i 0} {$i<10} {incr i} {
# Introduce a random delay
after [expr {int(5000 * rand())}]
update ;# Check for the asynch log switch
eval $script $i [clock clicks]
}
Note that in the most common case (where the script fragment is actually just a list of words forming a command prefix), it is better to |
use {*}$script when doing this sort of invocation pattern. It is less general than the eval command, and hence easier to make robust in |
practice. The following procedure acts in a way that is analogous to the lappend command, except it inserts the argument values at the
start of the list in the variable:
proc lprepend {varName args} {
upvar 1 $varName var
# Ensure that the variable exists and contains a list
lappend var
# Now we insert all the arguments in one go
set var [eval [list linsert $var 0] $args]
}
However, the last line would now normally be written without eval, like this: |
set var [linsert $var 0 {*}$args] |
