Talking REXX
All,
We are talking REXX, right? $ is not allowable in vars in REXX, so what are we talking?
Both "eval" and "interpret" work in REXX, but they have different formats, so you need to look in the manual for your version of REXX. There are several versions such as:
PREXX - Personal REXX
Regina - Another Personal REXX
OO-REXX - Official OO Rexx version (good docs)
Once you install you will enter "rexx cmdfile" at command line or for OO rexx enter the OO shell and execute the project. You can actually use OO rexx either way.
To display on screen, via command line, the "say" command, similar to PHP "echo" is used. Not eval or interpret.
Actually your script looks more like a PHP or PERL script than REXX. Is that what you are trying to do?
Let us know what else to help.

I am initiating a process from a mainframe using FTP. I'd like to use REXX statements in a CLIST to perform a capture of data from a UNIX system. Is there a "native" REXX language on UNIX. I've seen references for uni-REXX, OOREXX, S/REXX.
Thanks,

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] |
