This file is in the public domain.
exprfile(exp, link, ...)
produces a pipe to a program that writes all the
results generated by exp. The trailing arguments
name link files needed for the expression.
exprfile() closes any previous pipe it opened
and deletes its temporary file. Therefore,
exprfile() cannot be used for multiple expression
pipes.
If the expression fails to compile, the global
expr_error is set to 1; otherwise 0.
exec_expr(expr_list, links[])
generates the results of executing the expression
contained in the lists expr_list with the specified
links.
plst2pstr(L) converts the list of Icon programs lines in L to a
string with separating newlines.
pstr2plst(s) converts the string of Icon program lines (separated
by newlines) to a list of lines.
ucode(file) produces a ucode file from the Icon program in file.
