I first learned programming in BASIC on an 8K PET. The 8K was shared by the source code, data, the executing program and display memory.
Spaces were for suckers. Each line had a few bytes overhead so you put as many statements on each line as you could. You stuck to 1 character for your common variables (only 2 characters were significant anyway). You used the abbreviated name for commands. (This was around 81, 82.)
This is from memory, so probably not actually correct code but this is meant to print "IHN!" 10 times, wait about a second and then repeat. T is used as a FOR loop variable twice.

Something like this:
> 10 FORT=1TO10:?"IHN!":NEXTT:FORT=1TO1000:NEXTT:GOTO10"
