What functionality is supported in direct/interactive/immediate mode?

[Yet Another Troll]

Is XBasic 1.27-59 limited to four banger or adding machine (with ANS and other variables) functionality unless ? or PRINT is used? Also, spaces seem to be unexpectedly significant.

Thanks for your help!

Spaces are significant. If you want X11-Basic to calculate something, without assigning it to a variable or printing, the line has to start with a digit (0-9) otherwise the first word is interpreted as a command. so, do a 1*sqrt(2) instead.
Yes, the variable ANS will hold the result of the latest of such calculations.
