# values substituted for $(1) each time it is called.

# That resulting text is then eval'd.

#
|

# For most variables, you could use a single $ sign. The result
|

# is that the substitution would occur when the CALL occurs,
|
||||
# I believe. The problem is that the automatic variables $< and $@
|
||||
# need to be expanded-per-rule. Therefore, for those variables at
|
||||
# least, you need $$< and $$@ in the variable text. This way, after
|
||||
# the CALL substitution occurs, you will have $< and $@. This text
|
||||
# will then be evaluated, and all will work as you like.
|
||||
#
|
||||
# Reader beware, this explanantion could be wrong, but it seems to

# fit the experimental data (i.e., I was able to get the system

# working under these assumptions).
