This is a METAFONT problem.
 
I do not have access to a postscript printer and so I am interested in 
programs such as ps2mf. I found that this compiled without difficulty but I 
have had difficulty in using the mf file which it produces. 
 
The program takes a type1 postscript font and decompresses it and then 
converts it into (obscure) mf source. This reads in a file called hints.mf 
the code in which is even more obscure. When I run metafont on this it 
eventually, eg when it gets to letter W, crashes with a Metafont capacity 
exceeded, main memory size 65k or so, error.
 
I tried adding after each endchar the command showstats which showed that 
the memory was going down between characters; the log file contained the 
following---
 
**\mode=laserjet_high;input csrg
(adfs::4.$.MetaFont.Inputs.ps.mf.csrg 
(adfs::4.$.MetaFont.Inputs.ps.mf.hints)
exclam [33]
Memory usage unknown (21307 still untouched)
String usage 106&1201 (433&6695 still untouched)

ampersand [38]
Memory usage unknown (16307 still untouched)
String usage 106&1201 (424&6189 still untouched)
...
 
When it got to "W" the 'memory usage unknown still untouched' was down to a 
few hundred although the string usage remained more or less the same, and 
the error message appeared ....
 
I tried making the same alteration to romanu and running mf on cmr12 and 
noticed that the memory usage stayed the same throughout. 
 
I had assumed that since beginchar and endchar wrap each character in a 
begingroup and endgroup the mf memory usage would remain constant between 
characters. This appears to be wrong. Is there any way to restore the memory 
between characters?
