Re: When ctl-opt main() is missing

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

Thanks for the link, Gad. The article doesn't say anything about 
linear-main programs calling themselves, but it has a link in it to 
https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_74/rzasc/recursvhtm 
- this has more about calling linear-main recursively, which expands on 
what I found about a recursive call of a linear-main program is a 
dynamic program call. Here is that expansion -
