Should important commands in the present implementation of the ARexx port
not be present, you should contact me. In case they seem meaningful, I
will gladly implement them.
If you possess the commercial AmigaTEXversion: The few ARexx commands
present in its previewer are implemented in mine too. These are:
<#260#>getcwd<#260#> (equals <#261#>getdir<#261#>), <#262#>filename<#262#> (= <#263#>getfile<#263#>) and
<#264#>pagenum<#264#> (= <#265#>getpage<#265#>). <#266#>screen<#266#> and <#267#>exit<#267#> are present
anyway.
