Terminal-Multi-Line-Option

Add Terminal Multi-Line Option for IRIS and Caché
IRIS and Caché have just single command lines in terminal available

The Command extension enables execution of Multi Line Commands from Terminal prompt.

This is a coding example working on IRIS 2020.1 and on Caché 2018.1.3 
It will not be kept in sync with new versions      
It is also NOT serviced by InterSystems Support !   

Installation & Execution

Import %ZML.xml to Namespace %SYS

Optionally you may add this line to your %ZLANGC00.mac for simplified use:

ZML do ^%zml quit  ; add multi line command in terminal

otherwise just call it from terminal command prompt

  USER>do ^%zml

Usage

at the prompt USER:zml:1>
enter commands as usual
trigger execution by an empty line
stop multi line option with a single '.' (dot) at first position

Example

USER>zml
Entering multi line mode. Run with empty line. Stop with single "."
USER:zml:1> for i=1:1:20 {
USER:zml:2> write i
USER:zml:3> write ": "
USER:zml:4> if $x>70 write !
USER:zml:5> }
USER:zml:6> 1: 2: 3: 4: 5: 6: 7: 8: 9: 10: 11: 12: 13: 14: 15: 16: 17:
