Description

This function can be used to see whether an AIPS++ server tool exists or not. It relies upon the Glish tool having the function type which returns the name of the type of server. For example, ``quanta'' for a quanta server, or ``regionmanager'' for a regionmanager server. All of the AIPS++ servers (or tools) should have this function.

Example

- include 'quanta,g'
- include 'serverexists.g'  
- serverexists('dq', 'quanta', dq);
T
- symbol_delete('dq');
- serverexists('dq', 'quanta', dq);
F
